Hosmer-Lemeshow Test Visualization

Build Status Coverage Status Documentation

The performance of any binary classifier that provides a probabilistic output (rather than a binary value) can be visualized by splitting the target validation population into quantiles of a fixed count (usually 10, that is, deciles) and comparing the empirical incidence of the dependent variable to the probabilistic response outputted by the classifier. This is meant to represent a visualization of the Hosmer-Lemeshow goodness of fit test

The validationplot package makes this endeavour straightforward, especially in conjunction with the tundra package.
