Marquis Who's Who
Marquis Who's Who ( or ) is an American publisher of a number of directories containing short biographies. The books usually are entitled ''Who's Who in...'' followed by some subject, such as ''Who's Who in America'', ''Who's Who of American Women'', ''Who's Who in the World'', ''Who's Who in Science and Engineering'', ''Who's Who in American Politics'', etc. Often, ''Marquis Who's Who'' books are found in the reference section of local libraries, at corporate libraries, and are also used for research by universities.

Framingham Study
The Framingham Heart Study is a long-term, ongoing cardiovascular cohort study of residents of the city of Framingham, Massachusetts. The study began in 1948 with 5,209 adult subjects from Framingham, and is now on its third generation of participants. Prior to the study almost nothing was known about the epidemiology of hypertensive or arteriosclerotic cardiovascular disease. Much of the now-common knowledge concerning heart disease, such as the effects of diet, exercise, and common medications such as aspirin, is based on this longitudinal study. It is a project of the National Heart, Lung, and Blood Institute, in collaboration with (since 1971) Boston University. Various health professionals from the hospitals and universities of Greater Boston staff the project. History In 1948, the study was commissioned by Congress, with a choice made between Framingham, Massachusetts and Paintsville, Kentucky. Framingham was chosen when residents showed more general interest in heart resear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wake Forest University
Wake Forest University is a private university, private research university in Winston-Salem, North Carolina. Founded in 1834, the university received its name from its original location in Wake Forest, North Carolina, Wake Forest, north of Raleigh, North Carolina. The Reynolda Campus, the university's main campus, has been located north of downtown Winston-Salem since the university moved there in 1956. The Atrium Health Wake Forest Baptist medical campus has two locations, the older one located near the Ardmore neighborhood in central Winston-Salem, and the newer campus at Wake Forest Innovation Quarter downtown. The university also occupies lab space at Biotech Plaza at Innovation Quarter, and at the Center for Nanotechnology and Molecular Materials. The university's Wake Forest University School of Business, Graduate School of Management maintains a presence on the main campus in Winston-Salem and in Charlotte, North Carolina.

Wake Forest School Of Medicine
Wake Forest University School of Medicine is the medical school of Wake Forest University, with two campuses located in Winston-Salem, North Carolina and Charlotte, North Carolina, United States. It is affiliated with Atrium Health Wake Forest Baptist, the academic medical center whose clinical arm is Atrium Health Wake Forest Baptist. In 2021, ''U.S. News & World Report'' ranked Wake Forest School of Medicine 48th best for research in the nation and 80th best for primary care. The School of Medicine also ranks in the top third of U.S. medical schools in funding from the National Institutes of Health (NIH). Winston-Salem Campus History and background In 1902, the two-year Wake Forest College Medical School was founded on the college campus in Wake Forest, North Carolina. Thirteen students made up the charter medical class. Tuition was $37.50 per term; additional fees were charged for laboratories and student health care. The Southern Baptist denomination in 1919 began its first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The New England Journal Of Medicine
''The New England Journal of Medicine'' (''NEJM'') is a weekly medical journal published by the Massachusetts Medical Society. It is among the most prestigious peer-reviewed medical journals as well as the oldest continuously published one. History In September 1811, John Collins Warren, a Boston physician, along with James Jackson, submitted a formal prospectus to establish the ''New England Journal of Medicine and Surgery and Collateral Branches of Science'' as a medical and philosophical journal. Subsequently, the first issue of the ''New England Journal of Medicine and Surgery and the Collateral Branches of Medical Science'' was published in January 1812. The journal was published quarterly. In 1823, another publication, the ''Boston Medical Intelligencer'', appeared under the editorship of Jerome V. C. Smith. The editors of the ''New England Journal of Medicine and Surgery and the Collateral Branches of Medical Science'' purchased the weekly ''Intelligencer'' for $600 in ...

Normal Distribution
In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is : f(x) = \frac e^ The parameter \mu is the mean or expectation of the distribution (and also its median and mode), while the parameter \sigma is its standard deviation. The variance of the distribution is \sigma^2. A random variable with a Gaussian distribution is said to be normally distributed, and is called a normal deviate. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Their importance is partly due to the central limit theorem. It states that, under some conditions, the average of many samples (observations) of a random variable with finite mean and variance is itself a random variable—whose distribution converges to a normal dist ...

Goodness-of-fit
The goodness of fit of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected under the model in question. Such measures can be used in statistical hypothesis testing, e.g. to test for normality of residuals, to test whether two samples are drawn from identical distributions (see Kolmogorov–Smirnov test), or whether outcome frequencies follow a specified distribution (see Pearson's chi-square test). In the analysis of variance, one of the components into which the variance is partitioned may be a lack-of-fit sum of squares. Fit of distributions In assessing whether a given distribution is suited to a data-set, the following tests and their underlying measures of fit can be used: *Bayesian information criterion *Kolmogorov–Smirnov test *Cramér–von Mises criterion *Anderson–Darling test *Shapiro–Wilk test *Chi-squared test *Akaike informatio ...

D'Agostino's K-squared Test
In statistics, D'Agostino's ''K''2 test, named for Ralph D'Agostino, is a goodness-of-fit measure of departure from normality, that is the test aims to gauge the compatibility of given data with the null hypothesis that the data is a realization of independent, identically distributed Gaussian random variables. The test is based on transformations of the sample kurtosis and skewness, and has power only against the alternatives that the distribution is skewed and/or kurtic. Skewness and kurtosis In the following, denotes a sample of ''n'' observations, ''g''1 and ''g''2 are the sample skewness and kurtosis, ''mj''’s are the ''j''-th sample central moments, and \bar is the sample mean. Frequently in the literature related to normality testing, the skewness and kurtosis are denoted as and ''β''2 respectively. Such notation can be inconvenient since, for example, can be a negative quantity. The sample skewness and kurtosis are defined as : \begin & g_1 = \frac = ...
