The MULTTEST Procedure

STRATA Statement

The WEIGHT= option for the STRATA statement specifies the type of strata weighting to use when computing the Freeman-Tukey and t-tests for the mean. Valid values for the WEIGHT= option in the STRATA statement are SAMPLESIZE, HARMONIC, and EQUAL. SAMPLESIZE requests weights proportional to the within-stratum sample sizes, and is the default method. HARMONIC sets up weights equal to the harmonic mean of the non-missing within-stratum CLASS sizes, and is similar to a Type 2 analysis in PROC GLM. EQUAL specifies equal weights, and is similar to a Type 3 analysis in PROC GLM.
