LCA's estimation algorithm is very similar to Gaussian Mixture Modeling, so it's a quite easy jump from popular online EM content.

The project translates the functionalities of venerable polca R package. It's also nice to have polca as a reference package to validate output.

I use Python at work, so the algorithm themselves are written in C++...
