Terminating Intercept in Regression Analysis

[sasgiaz]

Hello. Does somebody happen to know what should be done if we're using regression analysis but the intercept is not significant?

If It should be terminated from the model, what syntax should we use?

Thank you for your kind help and attention.

would this help by using plots=fitplot

ods graphics on;
proc reg data=sashelp.class plots=fitplot;
model height=weight/noint;
run;
quit;

It's done! Thankyou so much!

Sorry if I bother you again.. But I found new problem.
I used to use the syntax like this:
model height=weight/influence;
and it has output statistics which has the value of model's residual, but I can't find it in the syntax you gave.
Could you tell me how to make the residual come out? Thanks before.

I would leave it in the model. The model will predict better and fit better.

[sasgiaz]

Could you tell me why is that?

Draw a plot of the regression line with the intercept.

Draw another plot of the regression line with no intercept.

See which one fits better visually.
