[Gretl-users] logistic regression model fit goodness test

Hello I have a few questions I've just started using GRETL. 1-GRETL program, the logistic regression (binary) model for the goodness of fit test hosmer-lemoshov statistic is not the cause of linear regression F statistic value. 2-Doesn't the program create logistic regression modeling of categorical sub-divisions of explanatory variables (eg 1-elementary, 2-high school, 3-associate…)? 3-Can't non-parametric tests be tested? Thank you.
