James Marquez's Analytics Portfolio

Welcome to my repository for sharing all things related to machine learning, predictive analytics, business analytics, and R/Python programming. Primarily, I write and share these articles as a tool I use to study/learn while researching each topic and as a resource for future projects. It's also a pleasure to pass on any knowledge I've gathered that may benefit others in their endeavors.
