R SQUARE explained:
In multiple linear regression, the indicator of how well a particular combination of X variables (the model drivers) explains the variation in Y (the dependent variable).
R square ranges in value from 0 to 1. A value of 0 means that the multiple linear regression model does nothing to explain the variation in Y. A value of 1 means that the model is a perfect fit. A value of 0.75 or more indicates an acceptable model.
R square is also known as the coefficient of determination or measure of goodness-of-fit.
There are two points to note when using R square:
R square is a nondescending function of the number of explanatory variables present in the model; that is, as you add more historical data and as you add more explanatory variables (X's), R square almost always increases and never decreases. This is because the addition of explanatory variables to the model causes prediction errors to be small. R square assumes that the data set being analyzed is the entire population. In fact, the data set represents only a sample of the populationMore terms such as R square in Dictionary R.
