Method = 1 (Strong Hierarchy) was chosen. The program 1. Standardizes all predictors to have mean 0 and variance 1 and renames them as x1-xp (see table below), numbered as they occur in the data set. 2. Fits main effects, interactions, and squared terms according to a modified forward selection procedure that on average has False Selection Rate (FSR) = .05. Developed by Hugh Crews, August 2008. Macro call parameters: Dataset = one Model = cd40|cd80|age|wtkg|karnof|hemo|homo|drugs|race|gender|str2|symptom @q Y = event Censor = censor Censorvalue = 0 Gamma = .05 Method = 1 Terms = 20 Include = 0 Cbound = none The number of effects forced into the model is 0. Note: The terms=k option was used. Suboptimal results may occur if k is so small that gammahat never reaches its maximum.
