Re: [R] Logistic Regression Fitting with EM-Algorithm

In view of your further explanation, Robin, the best I can offer is the following. [1] Theoretical frame. *IF* variables (X1,X2,X3) are distributed according to a mixture of two multivariate normal distributions, i.e. as two groups, each with a multivariate normal distribution, *AND* the members o

Re: [R] Logistic Regression Fitting with EM-Algorithm

Dear Ted, sorry for being unclear. Let me try again. I indeed have no knowledge about the value of the response variable for any object. Instead, I have a data frames of explanatory variables for each object. For example, x1 x2 x3 1 4.409974 2.348745 1.9845313 2 3.809249 2

[R] Logistic Regression Fitting with EM-Algorithm

Hi all, is there any package which can do an EM algorithm fitting of logistic regression coefficients given only the explanatory variables? I tried to realize this using the Design package, but I didn't find a way. Thanks a lot & Kind regards Robin Aly __
