E. J. G. Pitman
Edwin James George Pitman (29 October 1897 – 21 July 1993) was an Australian mathematician who made significant contributions to statistics and probability theory. In particular, he is remembered primarily as the originator of the Pitman permutation test, Pitman nearness anPitman efficiency His work ''the Pitman measure of closeness'' or ''Pitman nearness'' concerning the exponential families of probability distributions has been studied extensively since the 1980s by C. R. Rao, Pranab K. Sen, and others. The Pitman–Koopman–Darmois theorem states that only exponential families of probability distributions admit a sufficient statistic whose dimension remains bounded as the sample size grows. Biography Pitman was born in Melbourne on 29 October 1897, and attended University of Melbourne, residing at Ormond College, where he graduated with First Class Honours. In 1926 he was appointed Professor of Mathematics at the University of Tasmania, which he held until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ormond College
Ormond College is the largest of the residential colleges of the University of Melbourne located in the city of Melbourne, Victoria, Australia. It is home to around 350 undergraduates, 90 graduates and 35 professorial and academic residents. History Beginnings The University of Melbourne was established by an act of the Parliament of Victoria in 1853. were set aside for residential colleges, of which each were allotted to the Anglican, Presbyterian, Methodist and Roman Catholic denominations. The Presbyterian allotment became Ormond College. At the end of August 1877, Alexander Morrison, headmaster of Scotch College and convenor of the Presbyterian Church assembly's committee to "watch over the land", received a letter from the director of the Victorian Education Department, proposing that if the church did not mean to take the land for a college, that it be sold and the proceeds divided, half to the church and half to the state for university purposes. This spurred Morriso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Journal Of The Royal Statistical Society, Series A
The ''Journal of the Royal Statistical Society'' is a peer-reviewed scientific journal of statistics. It comprises three series and is published by Wiley for the Royal Statistical Society. History The Statistical Society of London was founded in 1834, but would not begin producing a journal for four years. From 1834 to 1837, members of the society would read the results of their studies to the other members, and some details were recorded in the proceedings. The first study reported to the society in 1834 was a simple survey of the occupations of people in Manchester, England. Conducted by going door-to-door and inquiring, the study revealed that the most common profession was mill-hands, followed closely by weavers. When founded, the membership of the Statistical Society of London overlapped almost completely with the statistical section of the British Association for the Advancement of Science. In 1837 a volume of ''Transactions of the Statistical Society of London'' were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historical Records Of Australian Science
''Historical Records of Australian Science'' is a biannual peer-reviewed academic journal covering the history of science in Australia and the south-west Pacific and published by CSIRO Publishing on behalf of the Australian Academy of Science. It was established in 1966 as an irregular publication with the title ''Records of the Australian Academy of Science'', obtaining its current name in 1980. Since then, the journal has appeared annually and, since 1991, twice a year. The editors-in-chief are Sara Maroske (Royal Botanic Gardens Melbourne) and Ian Rae (University of Melbourne).

Log-likelihood
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' ...

Statistical Society Of Australia
The Statistical Society of Australia (SSA) is the main professional organization for statisticians and related professionals in Australia. It was founded in 1962 to support and unify the work of Australian state statistical societies that were already in existence and had about 800 members in 2019. It has its own publishing arm, the Australian Statistical Publishing Association Inc. Its main publication is The Australian and New Zealand Journal of Statistics. The society currently has six state branches: Canberra, New South Wales, Queensland, South Australia, Victoria and Western Australia.
