Computes several information theory metrics between two vectors

It retrieves the same as var_rank_info but receiving two vectors. Metrics are: entropy (en), mutual information (mi), information gain (ig) and gain ratio (gr).

infor_magic(input, target)

Arguments

input

vector to be evaluated against the variable defined in 'target' parameter
target

vector containing the output variable.

Value

Matrix of 1 row and 4 columns, where each column represent the mentioned metrics

Examples

if (FALSE) {
infor_magic(data_golf$outlook, data_golf$play_golf)
}
