studentizev.

Brit.

/ˈstjuːdntʌɪz/,

/ˈstʃuːdntʌɪz/, U.S.

/ˈst(j)udnˌtaɪz/

Forms: 1900s– studentise, 1900s– studentize. Also with capital initial.

Origin: Formed within English, by derivation. Etymons: Student n.², -ize suffix.

Etymology: < Student n.² + -ize suffix; so called because of a resemblance to methods employed in the development of Student’s t-distribution.

Statistics.

transitive. To modify (a statistic or statistical procedure) in such a way that the result is independent of one or more unknown parameters; (esp. in later use) to modify (a statistic) by dividing it by an estimate of the standard deviation of the population.

1956 Proc. Third Berkeley Symp. Math. Statistics & Probability 2 90 I cannot at present see how to ‘Studentize’ the result in such a way that these parameters may be replaced by their estimates.
