Dear Roger and Valeska, I have example that uses Newton-Raphson for logistic regression in my R and S-PLUS Companion that might be of help. It's in the chapter script at <http://socserv.socsci.mcmaster.ca/jfox/Books/Companion/Ch8-script.txt> (the function lreg). See also the notes at <http://socserv.socsci.mcmaster.ca/jfox/Courses/S-course/Topic-4.pdf>.
I hope this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox -------------------------------- > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Roger D.
