LDA Precdict - Seems to be predicting on the Training Data
When I import a simple dataset, run LDA, and then try to use the model to forecast out of sample data, I get a forecast for the training set not the out of sample set. Others have posted this question, but I do not see the answers to their posts.

Jim has been exceedingly patient (and may well continue to be so), but this smells like "failure to launch".
