WebFor our example, this interpretation means that age, value of stock owned, number of employees supervised and house subsidy ALL have a large influence on the salary. So ALL these factors must be taken into account when we want to predict the salary (y). So the model is a good model to use to predict the salary. WebThe square root of this latter number is reported as the Root MSE. The model plus the residual sum of squares equals the total sum of squares, which is reported as 5789.1 in the last line of the table.

WebThe mean squared error (MSE) tells you how close a regression line is to a set of points. It does this by taking the distances from the points to the regression line (these distances are the “errors”) and squaring them. The squaring is necessary to remove any negative signs. It also gives more weight to larger differences. Webtable. The Root MSE is essentially the standard deviation of the residual in this model.
