In the effect summary of the logistic fit, I expected to see a logworth value for a p-value that appears to be zero. But 3 out of 4 parameters with p-values of zero did not have a logworth value. So I check the p-value with the scientific notation format and the 3 parameters without a log worth value were actual zero not a very small number close to zero. The RSquare (U) for this model is 1. I'm not sure what to make of this.
