PHREG Vs PROC REG

Shivi82 — Thu, 30 Oct 2014 17:14:53 GMT

Hi All,

I know this might sound an easy and new beginners questions however while i was working on multiple linear regression model i wanted to check the residuals and to create a graph for the same. During research I found both phreg and prog reg can be handy in doing so with some keywords added.

However I am a bit confused - what is the situation where i could use phreg and not proc reg and vice versa and both can be used.

Kindly advice.

Proc Phreg is for Survival analysis, when you have censored data.

Proc Reg is for regression analysis. If you want alternatives to Proc Reg consider Proc GLM.

I'd suggest mentioning the type of analysis you wanted to do and then looking at the type of procs that are appropriate.

Try proc reg/proc glm, proc phreg was designed to do Cox regression analysis of continuous-time survival data.
