Proc Reg models

Jado — Tue, 16 Feb 2021 23:13:48 GMT

I want to write a code to create a regression model. the outcome is continuous, but the independent variable is categorical.

I tried this code:

proc reg;
model cognitive = race;
run;

but it is considering race as a continuous variable.

how can I tell SAS that race is categorical?

I have 2 races

Use GLM instead:

proc glm;

class race;
model cognitive = race;
run;

Use proc glm and define race as a class variable. BTW, that particular form of regression is called Analysis of Variance (ANOVA).
