Re: Significance tests for logistic regression

Okay, have played with the factor coding in the GLZM module and if set the factors to be "Dummy" I retrieve the same results as from the binomial logistic regression (both factors contained either "a" or "b" for each observation. So that has solved that - thanks! Intere...

Re: Significance tests for logistic regression

Thanks for getting back in touch. I think I see what you are getting at, although I have two queries. First, the main problem I have is that a binomial logistic regression is a generalised linear model with a logit link function and binomial errors, and if I run a GLZM on 0,1 data surely it should g...

Significance tests for logistic regression

Apologies if this has come up before, but I could not see it. If I run a binary logistic regression using the "Binomial Logistic Regression" from the "Regression" tab I get different results to an analysis run using the "Generalised Linear Models" from the "Linear ...
