Student's t distribution

English Alternative forms en Student's t-distribution Etymology From the pen-name of Irish statistician William Sealy Gosset, which he used for a 1908 paper in Biometrika, under the pseudonym en Student. The distribution was popularised through the work of en Ronald Fisher, who referred to it as Student's distribution and used the letter t to represent the test value. Noun Student's t distribution en statistics A distribution that arises when the population standard deviation is unknown and has to be estimated from the data. en 2009 Francesco Sardanelli; Giovanni Di Leo Biostatistics for Radiologists: Planning, Performing, and Writing a Radiologic Study [2008, Biostatistica in Radiologia] Springer https://books.google.com.au/books?id=bVknKyVUaBcC&pg=PA59&dq=%22Student%27s+t-distribution%22%7C%22Student%27s+t-distributions%22&hl=en&sa=X&ved=0ahUKEwj5r9PDpJrWAhUrqVQKHR2IAlAQ6AEIzQEwHw#v=onepage&q=%22Student's%20t-distribution%22%7C%22Student's%20t-distributions%22&f=false 59 A complete description of the Student's t distribution is beyond the aims of this book. en 2011 Rand Wilcox Modern Statistics for the Social and Behavioral Sciences: A Practical Introduction Taylor & Francis (CRC Press) https://books.google.com.au/books?id=Yj5LKoBq9ZUC&pg=PA155&dq=%22Student%27s+t-distribution%22%7C%22Student%27s+t-distributions%22&hl=en&sa=X&ved=0ahUKEwj5r9PDpJrWAhUrqVQKHR2IAlAQ6AEIrwEwGg#v=onepage&q=%22Student's%20t-distribution%22%7C%22Student's%20t-distributions%22&f=false 155 In contrast, the 0.95 confidence interval for μ is (577.1,623.4), assuming T does indeed have a Student's t distribution. en 2012 Paul D.

Usage notes Sometimes referred to as Student's t distribution (a noun phrase with Student's used as determiner). The isolated letter t is often italicised.
