Summary The estimation of the regression coefficient of a population, defined byE (y)= γ+βx, incorporating two preliminary tests of significance has been discussed. The experimenter has two random samples of different sizes from two such populations, as defined above, with regression coefficientsβ 1 andβ 2 respectively, whereβ 2 may possibly be equal toβ 1. Besides this, it is also conjectured that the common conditional varianceσ 2 of the two populations has a specified valueσ 0 2 . The two preliminary tests are used to resolve these two uncertainties.
