explain model in glm

sas_newbie3 — Tue, 14 Mar 2017 11:18:12 GMT

Hi,

I don't understand the model in glm. Say.

proc glm data=mydata;
	class name;
	model a b c d = name;
	ods output modelanova=myanova;
run;

I am not sure the meaning of "=" in the line of model.

Can we rewrite the code as

	model a =name b c d;

model a b =name c d;

In model statements the variable(s) to the left of = are dependent variables and those on the right are independent. So a basic statement like

model a = x y z;

Says build a model that "predicts" values of a using variables x y and z.

Depeding on the procedure many will not allow multiple dependent variables.

model a b c d = name;

It is right model, a.k.a  multi-variables ANOVA.

There is an excellent example in documentation to describe this kind of model.
