I know p-value is a 4-letter word nowadays but I still decided to derive some for my current model.

I'm assuming that all I need to do is examine the change in likelihood between

c#1 c#2 c#3 on covariate;

and

c#1 c#2 c#3 on covariate@0;

and derive a chi-square stat from this.


Experimenting with a simple logistic model and comparing results with SPSS showed that the results were not in total agreement (although reasonably close) so i wonder if I'm not doing this exactly right.

Many thanks


Jon

-2 times the loglikelihood difference is approximately equal to z square.

Simple as that!
Many thanks
