Q
Assumptions of Multiple Regression
A
- Correct specification of the relation between independent variables and
dependent variable - Correct specification of the independent variables in the regression
model - No measurement errors in the independent variables (reliable
measurements) - Constant variance of residuals (homoscedasticity)
- Residuals are independent of each other
- Residuals are normally distributed
- No outliers
- No multicollinearity
