sklearn.metrics.mean_squared_error — scikit-learn. – or array-like of shape (n_outputs) Defines aggregating of multiple output values. Array-like value defines weights used to average errors. ‘raw_values’ :

Jul 11, 2015. The variance measures how far a set of numbers is spread out whereas the MSE measures the average of the squares of the "errors", that is, the difference between the estimator and what is estimated. The MSE of an estimator ˆθ of an unknown parameter θ is defined as E[(ˆθ−θ)2]. The MSE is the second.

Here’s how to calculate the root mean square error. Assume you have one set of numbers that represent the Actual values you want to predict. Actual = [1 2 3 4.
