Hello,   I have a question about how to interpret the SAS EM output on Analysis of Maximum Likelihood Estimates from linear regression model.  Our model has 2 predictors (i.e., var1 and var2). We used the opt binning transformation on var2. We used 4 bins for VAR2.  The coefficients from my selected regression model for variables are: INTERCEPT = 1.234 VAR1 = 0.2 OPT_VAR2 01 =  0.111 OPT _VAR2 02 = 0.22 OPT _VAR2 03 = 0.32    OPT_VAR2 04 BIN was not included in the selected model.  We are hoping for help to determine the missing piece of the following equation: Outcome = intercept + 0.2VAR1 + ???  Thanks,   Will ...
