calculateConfusionMatrixStats R Documentation
Calculates multiple confusion matrix stats from mariginal probabilities in dplyr friendly manner
Description
The purpose of this is to make it possible to calculate accuracy stats in a DPLYR table (including dbplyr). Typically
this will come from some sort of threshold based classification task where the classification output
is a probability and the prediction class is a binary outcome.
Usage
calculateConfusionMatrixStats(df)
Arguments
df
a dataframe containing one observation per row & p_x1y1, p_x0y1, p_x1y0, and p_x0y0 columns (see probabilitiesFromConfusionMatrix)
Details
see also fBeta score vectorised function
Value
the datatable with additional columns for confusion matrix stats: true_pos_rate / true_neg_rate / etc...
