About

Greetings. I’m Paul Johnson, a professor of political science at the University of Kansas. I work also in the Center for Research Methods and Data Analysis, where we do consulting on statistical and computational problems.

My homepage is http://pj.freefaculty.org. If you are looking for help with R stuff, please see http://pj.freefaculty.org/R. If you are looking for my statistics lectures, I’m pooled everything under http://pj.freefaculty.org/guides. If you don’t find something there, there is a good chance I did not write it yet. Or I wrote it so long ago it is not even in my version management system.

    Dear Paul,

    I’m questioning about rare events in logistic regression and I was wondering if you have the answer to the question you asked in a previous post : “how the bias correction links to mixed models ?”

    Thanks

    Anais
