I am recently researching crises and the usefulness of different models in predicting them. It would be nice to have some help from any of you guys regarding Stata using categorical panel data.
I am interested in the following:

1) Any books which explain categorical data in detail - especially how to build a model and predict events

2) Any websites that contain lessons regarding categorical panel data

3) Any websites where I can find academic papers and their databases and do files to replicate them

Thanks in advance.
