RECOVERING INFORMATION IN AUGMENTED DESIGNS, USING SAS PROC GLM AND PROC MIXED

The SAS GLM and MIXED procedures can be useful for experimenters desir ing to analyze data from screening experiments using a member of the c lass of augmented experiment designs. Since application of the procedu res is typically not straighfforward for these designs, several progra ms of possible interest are described, We show how to recover interblo cking and intervariety information when the blocking and varieties are random effects, how to arrange varietal responses in descending order , and a number of other options.
