R help - Mar 2010 - calculate response probabilities using sem-analysis

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 probability of
response. How can I calculate these probabilities?
I tried to use the unstandardized coefficients, just like a regression
coefficient in the following formula:
Y = b1*x1 + b2*x2
But then I have values larger than 1, so that aren't probabilities. Does
anyone dealt with this problem before?
You can be of great help to me!!

Kind regards,

Tryntsje
