Abstract
We also obtain some necessary conditions forhat mu to have a variance smaller than that ofx It can be seen that with the exception of linked block designs for any design belonging to the class calledD1class by Shah 16 YatesRao estimator for recovery of interblock information has the same form as that ofhat mu Hence for such designs the above results can be used to examine if Yates estimator is good ie better than the intrablock estimator Shah 16 resolved this question for linked block designs which include the symmetrical BIBDs Here we consider asymmetrical BIBDs and show that Yates estimator is good for all such designs listed in Fisher and Yates table 5 with two exceptions For one of these two designs we show that Yates estimator is not uniformly better than the intrablock estimator
