`mstools`¶

mstools.py module.

Contains the functions and routines that are often used but are not included in current common packages. It may include code used in different areas of knowledge.

mstools.mstools.r2_score(y_true, y_pred)[source]¶

Calculate the coefficient of determination (\(R^2\)).

\(R^2\), pronounced “R squared”, is the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

Parameters

y_true (List, tuple or array) – Actual value of the predictied variable.
y_pred (List, tuple or array) – Predicted value from the linear regression model.

Returns

Coefficient of determination (\(R^2\)).

Return type

float

Examples

>>> y_true = [1, 2, 3, 4, 5]
>>> y_pred = [1.1, 2.3, 2.8, 4.1, 4.9]
>>> r2_score(y_true, y_pred)
0.984
