Assumptions testing of Linear regression on SAS Eminer

Prajna_450 — Wed, 07 Dec 2016 11:11:17 GMT

Hi team,

I am working on a client data and would be interested to see if eminer can support me to check the assumptions of a linear regression.

some thing like test linearity, multivariate normality, multicollinearity, auto correlation and homoscadasticity.

I may have alternative platforms to perform the exercise but I want to know if sas eminer nodes can provide these results. I have tried to seek these results in excel. kindly guide

Thank You,

Prajna.T

You covered many statistical models:

 test linearity, -- Check PROC REG,PROC CORR

 multivariate normality,

multicollinearity,--Check PROC REG's VIF

 auto correlation and homoscadasticity.
--Check PROC AUTOREG PROC MODEL, you need SAS/ETS .
