Lecture 7: Multiple Regression Flashcards
1
Q
Difference between bivariate and multiple regression
A
Bivariate accounts for variance in criterion using one predictor, multiple uses more than one predictor
2
Q
Validities
A
Show whether our predictors are valid predictors for our criterion
3
Q
Tolerance (TOL) < .2 indicates what
A
multicollinearity, which we do not want , therefore we want TOL greater than .2
4
Q
Variable inflation factor (VIF) > 5 indicates what
A
multicollinearity, which we do not want, therefore we want VIF less than 5
5
Q
What SPSS table is looked at for predictive utility in multiple regression
A
ANOVA
6
Q
sr^2 ( squared semi partial correlation) tell us
A
Proportion of unique variance accounted for
7
Q
sr
A
Part correlation
