Everything about Studentization

In statistics, Studentization, named after William Sealy Gosset, who wrote under the pseudonym Student, is the process of dividing a statistic derived from a sample by a sample-based estimate of a population standard deviation. Unlike "normalization", where only the numerator is uncertain, Studentization has both numerator and denominator uncertain, typically following a Student-T distribution. The term is also used for the standardisation of a higher-degree statistic by another statistic of the same degree: for example, an estimate of the third central moment would be standardised by dividing by the cube of the sample standard deviation.
