I want to run probit and logit model through SPSS. I have categorical dependent variable and mixed (categorical and continuous) independent variables. When I go to screen board on the SPSS sight for logit model calculation, it shows response frequency, total observed, factor, and co-variate(s). I understand about response frequency and co-variate(s), but do not understand about factor and total observed. what tell these variable and how it decided about these variable. how can I know that in my data who in factor and who is total observed variable. How can I run this model?
