[R] calculate response probabilities using sem-analysis

2010-03-22 Thread Tryntsje Wesselius
Hi everyone, I just conducted a structural equation model for estimating a response model. This model should predict the probability that someone is responding to a direct mailing. I used the sem package for this. When I have my coefficients I want to know how well my model predicts the probabilit

Did you back-calculate to estimate an intercept? Alternately, I've been working on a function that takes a fitted sem and gets predicted values given an input. Contact me off-list and I'll send it to you. On Mar 22, 2010, at 8:37 AM, Tryntsje Wesselius wrote: Hi everyone, I just conducte
