One way to get standardized beta coefficients is to center and scale all of the x variables (subtract the mean then divide by the standard deviation), then fit the regression on the standardized x's. You could do the same thing with a robust regression (these values may not be meaningful if there

[R] results of robust regression vs. OLS regression

2013-07-09 Thread D. Alain
Dear R-List, due to outliers in my data I wanted to carry out a robust regression. According to APA standards, reporting OLS regression results should include   1. unstandardized beta coefficients 2. standardized beta coefficients 3. SE 4. t values 5. r squared 6. r squared adjusted 7. F (df.num
