Expand description

Regression metrices trait for multiple targets.

It is possible to compute the listed mectrics between:

  • bi-dimensional array - bi-dimensional array
  • bi-dimensional array - dataset
  • dataset - dataset
  • dataset - one-dimensional array
  • dataset - bi-dimensional array

The shape of the compared targets must match.

To compare single-dimensional arrays use SingleTargetRegression

Provided methods

Maximal error between two continuous variables

Mean error between two continuous variables

Mean squared error between two continuous variables

Mean squared log error between two continuous variables

Median absolute error between two continuous variables

R squared coefficient, is the proportion of the variance in the dependent variable that is predictable from the independent variable

Same as R-Squared but with biased variance
