LOOCLASS: Stata module for generating classification statistics of Leave-One-Out cross-validation for binary outcomes

Abstract: looclass performs leave-one-out cross-validation for regression and machine learning models with a binary outcome and then produces classification measures to assist in determining the error rate (or conversely, the accuracy) of a prediction (classification) model. Leave-one-out cross-validation is n-fold cross-validation, where n is the number of observations in the dataset. Each observation in turn is left out, and the given model is estimated for all remaining observations. The predicted value is then calculated for the one hold-out observation, and the accuracy is determined as success or failure in predicting the outcome for that observation. The results of all n predictions are used to calculate the final error estimates (accuracy) displayed in the classification table and ROC analyses generated by looclass.
