I attended a talk about Jupyter from one of the main developers, and after explaining what Jupyter is, he demonstrated JupyterLab.

This page gives a nice tutorial introduction to lavaan, the R package for SEM, and the material is pitched at a level easy to follow even for people like me who have a limited appreciation for SEM terminology.

Unfortunately, many of the books and websites that I have looked at use examples in C and FORTRAN. These are fine languages, but ones that I am unlikely to need in the future. I want to explore MPI from with a newer programming language, Python. Here are some resources I have leaned on in getting this started. Continue reading
