Ratio of correct prediction

Hi,
I used Mplus to solve simultaneous logistic regression models as the follows,
I want to know if and how I can get the ratio of correct prediction of the models, in addition to the goodness of fit of the model. (I have read through the Mplus manuals but failed to work it out).

i.e., I want to know how well the models predict, in terms of percentage of correct prediction.

Percentage correct prediction can be obtained by comparing the estimated probability for a subject with the observed 0/1 outcome. How to get the estimated probability is shown on our book page

http://www.statmodel.com/mplusbook/chapter5.shtml

See the input/output for 5.11 (Part 2) and 5.11 (Part 3).

There is no generally accepted overall goodness of fit measure for logistic regression.

Hi Bengt,
Thanks for reply. I tested and found the accuracy of predicted values is 1. That means the "propensity" output/save is not the estimated values by the model, but the original data.

Did I miss something? Look forward to hearing from you soon. Thanks again.

Propensity is the estimated probability. If this doesn't help, send relevant files to Support along with your license number.
