I am using proc reg to generate regression coeff's. Is there an easy way to programmatically get these coeffs, or do I just need to read them from the output and type into code each time I run?
If you want to use these values in a regression equation, you would need the PROC REG option OUTEST= and then you could use PROC SCORE to make use of the regression equation.
OR did you have some other use in mind for the regression coefficients?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
