1938Suppl. Jrnl. R. Statistical Soc. V. 80 This theory has been developed further, and quite a number of large-sample results have been ‘studentized’. By this we mean that a statistic whose sampling distribution involves the unknown standard deviation of the population is modified so that its distribution involves only quantities calculated from the sample. 1939Biometrika XXXI. 21 In a recent paper H. O. Hartley..has suggested a systematic method of obtaining probability levels for ‘studentized’ functions. 1957Kendall & Buckland Dict. Statistical Terms 284 Studentisation, the process of removing complications due to the existence of an unknown parent scale-parameter by constructing a statistic whose sampling distribution is independent of it; especially by dividing a statistic which is of a certain degree in the observations by another statistic of the same degree. 1959H. Scheffé Analysis of Variance ii. 28 In the next chapter we will apply the distribution of the Studentized range. 1972Biometrika LIX. 165 Duncan's modification also starts with the studentized range test. |
