Missing plots in analysing randomized block design

Abstract

Attempt has been made to find out the practical implication of some methods for analysing randomized block design with missing observations. Nine methods have been examined. In fact, all the methods quite agree to the first place of decimals and approximately to the second place of decimals in estimating missing plots. The covariance method is the quickest method to get the estimation of the missing plots. Fitting missing values by a coverince adjustment an old method possibly on account of the proliferation of Computer programs make covariance adjustments without difficulty.
