i am exploring SAS Enterprise Miner right now. i am working with proc Genmod.
Analysis Of Maximum Likelihood Parameter Estimates
Standard Wald 95% Confidence
Parameter DF Estimate Error Limits
Intercept 1 -2.5659 0.0666 -2.6964 -2.4354
Brand PBB 1 1.0135 0.0804 0.8559 1.1711
Brand PFl 1 -0.2243 0.0991 -0.4185 -0.0301
Brand PGen 1 0.2179 0.0901 0.0413 0.3945
Brand PHse 1 0.9059 0.0814 0.7465 1.0654
Brand PPk 1 2.3614 0.0750 2.2145 2.5083
Brand PSS 0 0.0000 0.0000 0.0000 0.0000
Scale 0 1.0000 0.0000 1.0000 1.0000
NOTE: The scale parameter was held fixed.
to my understanding, i am reading the output like, for example for Brand PPk estimate is 2.3614. that means this brand is 2.3614 likely to be the choice than the other 5. and for brand PSS its 0.0000 that means it was never choosed.
Am i right in onterpreting the results???
Posterior Correlation Matrix

Parameter Intercept PBB PFl PGen PHse PPk
Intercept 1.000 -0.829 -0.688 -0.738 -0.820 -0.888
BrandPBB -0.829 1.000 0.566 0.617 0.676 0.742

BrandPPk -0.888 0.742 0.609 0.653 0.727 1.000
for this posterior corelation matrix, output will be interprted as for example, Brand PBB and Brand PPk are strongly corelated as 0.742 is close to 1. ????
