https://communities.sas.com/t5/Statistical-Procedures/ANOVA-and-REG/m-p/74158#M3562 I am creating a regression model, I find there is some difference between the GLM procedure(ANOVA) and REG procedure, which one should I use to creat a model?<BR /> And how to interepret them?<BR /> Any suggestion is appreciated.

Software can estimate the parameters in your models.
