The regression can reduce the unknown elements to just the sum of squared Errors, e’e. The amount of sum of squares that the regression explains is the difference: SST-SSE=SSR. R2 is a common measure of performance (also called the coefficient of determination:

Multiple Regression Case. In the previous reading assignment the ordinary least squares (OLS) estimator for the simple linear regression case, only one independent variable (only one x), was derived. The procedure relied on combining calculus and algebra to minimize of the sum of squared deviations.

3. Multiple regression. Multiple regression is just an expansion of simple linear regression. In simple linear regression, you fit a straight line using dependent (y) and independent (x) variables: Y=m1x + b. In multiple regression, you simply throw in a second independent variable as …

Multiple regression is a set of techniques for generating a predicted score for one variable from two or more predictor variables. And the nice thing about multiple regression is that it’s just an extension of regression with one predictor variable.

Definition of multiple regression analysis: The development of a combination rule relating a single dv to two or more IV’s so as to . maximize the “correspondence” between the dv and the combination. of the iv’s. Correspondence: Least squares criterion.

ΔR2 is the incremental increase in the model R2 resulting from the addition of a predictor, or set of predictors, to the regression equation. 2. Example. Model 1 (Reduced model) Test Scores = b0 + b1 (IQ) + e. DV = Student Reading Test Scores. IV 1 = IQ. Model 2 (Full model) Test Scores = b0 + b1 (IQ) + b2 (Study Time) + e. DV = Student ...

which is ordinary multiple regression. We have a very similar equation on the criterion side: Note that in general, the regression weights a and bi will not be the same on the judgment side and the criterion side. On the judgment side, we can find an R-square, which is …
