Quizplus · Accepted Answer

The mean square error (MSE) is a measure of the accuracy of a forecasting model. It measures the average of the squares of the errors, which are the differences between the forecast and the actual values. A lower MSE indicates better accuracy. Therefore, option C is the correct choice. The other options are not directly related to measuring the accuracy of a forecasting model.
