Meadow's Law
Now discredited, Meadow's Law was a precept much in use until recently in the field of child protection, specifically by those investigating cases of multiple cot or crib death – SIDS – within a single family. History The "law" has it that because such deaths are a rare phenomenon and difficult to explain by natural causes, we might say that "One is a tragedy, two is suspicious and three is murder unless there is proof to the contrary." The name is derived from the controversial British paediatrician, Roy Meadow, who until 2003 was seen by many as "Britain's most eminent paediatrician" and leading expert on child abuse. Meadow's reputation went into decline with a series of legal reverses for his theories, and the damage was confirmed in July 2005 when he was struck off the medical register by the General Medical Council for tendering misleading evidence. Meadow's license was reinstated in February 2006 by a London court. Meadow attributes many unexplained infant deaths to t ...

Sudden Infant Death Syndrome
Sudden infant death syndrome (SIDS) is the sudden unexplained death of a child of less than one year of age. Diagnosis requires that the death remain unexplained even after a thorough autopsy and detailed death scene investigation. SIDS usually occurs during sleep. Typically death occurs between the hours of midnight and 9:00 a.m. There is usually no noise or evidence of struggle. SIDS remains the leading cause of infant mortality in Western countries, contributing to half of all post-neonatal deaths. The exact cause of SIDS is unknown. The requirement of a combination of factors including a specific underlying susceptibility, a specific time in development, and an environmental stressor has been proposed. These environmental stressors may include sleeping on the stomach or side, overheating, and exposure to tobacco smoke. Accidental suffocation from bed sharing (also known as co-sleeping) or soft objects may also play a role. Another risk factor is being born before 39 ...

Probability
Probability is the branch of mathematics concerning numerical descriptions of how likely an Event (probability theory), event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty."Kendall's Advanced Theory of Statistics, Volume 1: Distribution Theory", Alan Stuart and Keith Ord, 6th Ed, (2009), .William Feller, ''An Introduction to Probability Theory and Its Applications'', (Vol 1), 3rd Ed, (1968), Wiley, . The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written ...

Kathleen Folbigg
Kathleen Megan Folbigg (Married and maiden names, née Donovan; born 14 June 1967) is an Australian woman convicted in 2003 for killing her four infant children. She was pardoned twenty years later due to serious doubts that had arisen about her guilt. No direct evidence of the imputed crimes was ever found, but in the personal diary discovered by her husband and dutifully handed over to the police, several entries seemed to suggest she might have harmed, and indeed murdered, her children. She was arrested in 2001 and convicted in 2003, sentenced to 40 years with a non-parole period of 30 years. Kathleen Folbigg maintained her innocence, however, claiming the four children had died from natural causes. Scientific and medical research suggesting the daughters might indeed have died of natural causes was rejected by a judicial inquiry in 2019. Subsequent research published in 2020 led ninety eminent Australian scientists and medical professionals, in March 2021, to petition the Go ...

Guilt (law)
In criminal law, guilt is the state of being responsible for the commission of an offense. Legal guilt is entirely externally defined by the state, or more generally a "court of law". Being "guilty" of a criminal offense means that one has committed a violation of criminal law, or performed all the elements of the offense set out by a criminal statute. The determination that one has committed that violation is made by an external body (a "court of law") after the determination of the facts by a finder of fact or “factfinder” (i.e. a jury) and is, therefore, as definitive as the record-keeping of the body. For instance, in the case of a bench trial a judge acts as both the court of law and the factfinder, whereas in a jury trial the jury is the trier of fact and the judge acts only as the trier of law. Thus, the most basic definition is fundamentally circular: a person is guilty of violating a law if a factfinder in a court of law so says. Philosophically, guilt in criminal ...

Verdict
In law, a verdict is the formal trier of fact, finding of fact made by a jury on matters or questions submitted to the jury by a judge. In a bench trial, the judge's decision near the end of the trial is simply referred to as a finding. In England and Wales, a coroner's findings used to be called verdicts but are, since 2009, called conclusions (see ). Etymology The term "verdict", from the Latin ''veredictum'', literally means "to say the truth" and is derived from Middle English ''verdit'', from Anglo-Norman language, Anglo-Norman: a compound of ''ver'' ("true", from the Latin ''vērus'') and ''dit'' ("speech", from the Latin ''dictum'', the Grammatical gender, neuter past participle of ''dīcere'', to say). Criminal law In a Criminal law, criminal case, the verdict, which may be either "not guilty" or "guilty"—except in Scotland where the verdict of "not proven" is also available—is handed down by the jury. Different counts in the same case may have different verdicts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Murder
Murder is the unlawful killing of another human without justification or valid excuse, especially the unlawful killing of another human with malice aforethought. ("The killing of another person without justification or excuse, especially the crime of killing a person with malice aforethought or with recklessness manifesting extreme indifference to the value of human life.") This state of mind may, depending upon the jurisdiction, distinguish murder from other forms of unlawful homicide, such as manslaughter. Manslaughter is killing committed in the absence of ''malice'',This is "malice" in a technical legal sense, not the more usual English sense denoting an emotional state. See malice (law). brought about by reasonable provocation, or diminished capacity. ''Involuntary'' manslaughter, where it is recognized, is a killing that lacks all but the most attenuated guilty intent, recklessness. Most societies consider murder to be an extremely serious crime, and thus that a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosecutor's Fallacy
The prosecutor's fallacy is a fallacy of statistical reasoning involving a test for an occurrence, such as a DNA match. A positive result in the test may paradoxically be more likely to be an erroneous result than an actual occurrence, even if the test is very accurate. The fallacy is named because it is typically used by a prosecutor to exaggerate the probability of a criminal defendant's guilt. The fallacy can be used to support other claims as well – including the innocence of a defendant. For instance, if a perpetrator were known to have the same blood type as a given defendant and 10% of the population to share that blood type, then one version of the prosecutor's fallacy would be to claim that, on that basis alone, the probability that the defendant is guilty is 90%. However, this conclusion is only close to correct if the defendant was selected as the main suspect based on robust evidence discovered prior to the blood test and unrelated to it (the blood match may th ...

Statistician
A statistician is a person who works with theoretical or applied statistics. The profession exists in both the private and public sectors. It is common to combine statistical knowledge with expertise in other subjects, and statisticians may work as employees or as statistical consultants. Nature of the work According to the United States Bureau of Labor Statistics, as of 2014, 26,970 jobs were classified as ''statistician'' in the United States. Of these people, approximately 30 percent worked for governments (federal, state, or local). As of October 2021, the median pay for statisticians in the United States was $92,270. Additionally, there is a substantial number of people who use statistics and data analysis in their work but have job titles other than ''statistician'', such as actuaries, applied mathematicians, economist An economist is a professional and practitioner in the social science discipline of economics. The individual may also study, develop, and apply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Statistical Independence
Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes. Two events are independent, statistically independent, or stochastically independent if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect the odds. Similarly, two random variables are independent if the realization of one does not affect the probability distribution of the other. When dealing with collections of more than two events, two notions of independence need to be distinguished. The events are called pairwise independent if any two events in the collection are independent of each other, while mutual independence (or collective independence) of events means, informally speaking, that each event is independent of any combination of other events in the collection. A similar notion exists for collections of random variables. Mutual independence implies pairwise independence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Likelihood Function
The likelihood function (often simply called the likelihood) represents the probability of random variable realizations conditional on particular values of the statistical parameters. Thus, when evaluated on a given sample, the likelihood function indicates which parameter values are more ''likely'' than others, in the sense that they would have made the observed data more probable. Consequently, the likelihood is often written as \mathcal(\theta\mid X) instead of P(X \mid \theta), to emphasize that it is to be understood as a function of the parameters \theta instead of the random variable X. In maximum likelihood estimation, the arg max of the likelihood function serves as a point estimate for \theta, while local curvature (approximated by the likelihood's Hessian matrix) indicates the estimate's precision. Meanwhile in Bayesian statistics, parameter estimates are derived from the converse of the likelihood, the so-called posterior probability, which is calculated via Bayes' r ...
