For instance, if β 1 = .6, and β 2 = .3, then the first explanatory variable is twice as important as the second. While this idea is appealing, unfortunately, it is not valid. WebThe SAS Input Data Setcontains all of the numeric data to be analyzed. Three other data sets can be specified: The Standardization Statistics Input SAS Data Set, needed when DATASETis chosen as the Standardization Method. It contains location and scale estimates by which to standardize the Input SAS Data Set.
