Trying to find the relationship between AGE (continuous) and GENDER (categorical) variables in my dataset using SAS (v9.4). I used the below code.   proc glm data = myfile; class GENDER;  model AGE = GENDER / solution; run;   How to verify if the LINE assumptions of a linear regression model are met or violated in the above case (using SAS)? L - Linear I - Independent N - Normality E -Equal Variance   Please provide the SAS code to be able to do that. ... View more

I have a dataset that contains several variables from which, I'd like to know if the mean AGE in the "population" vary by GENDER, while controlling for RACE?   In this case Y = AGE (continuous variable) X1 = GENDER and X2 = RACE (both X1 and X2 are categorical variables) Since the question asks about "population" and not sample, I chose to use weight variables. However, I am not sure how to let SAS know that I am controlling for a variable "RACE"?   This is what I am using as of now...   proc surveyreg data = myfile;  class GENDER RACE;  weight weightvariable;  strata stratavariable;  cluster clustervariable;  model AGE = GENDER RACE / solution; run; ...
