WebMean squared error (MSE) measures the amount of error in statistical models. It assesses the average squared difference between the observed and predicted values. When a model has no error, the MSE equals zero. As model error increases, its value increases. WebThe mean squares (MS) column, as the name suggests, contains the "average" sum of squares for the Factor and the Error: The Mean Sum of Squares between the groups, denoted MSB , is calculated by dividing the Sum of Squares between the groups by the between group degrees of freedom.
