Creates a matrix of features and target based on the values from contingency matrix.
create_feature_target(n11, n01, n10, n00)
n11 | number of elements for which both target and feature equal 1. |
---|---|
n01 | number of elements for which target and feature equal 1,0 respectively. |
n10 | number of elements for which target and feature equal 0,1 respectively. |
n00 | number of elements for which both target and feature equal 0. |
a matrix of 2 columns and n11+n10+n01+n00 rows. Columns represent target and feature vectors, respectively.
