Predictive Analytics

A classification web app that gives predictions, cross-validation score, and principal component plot.


The user can upload a clean csv file and select the features and response variables. The app will fit a logistic regression through the data. More methods will be introduced in the future. Update: Now include both 2D and 3D PCA plots! 7/17/2018
