title: [The power and sample size of F tests of variance proportions in multiple regression].
abstract: We would consider not only the significance level alpha, but also the power 1-beta, when making a significance test. This paper presents the method of finding the power of the significance test of a multiple regression equation, and the method of finding the necessary sample size, and has listed the power table and the sample size table for ready reference.
