How to output the confidence intervals (of conditional mean) and prediction intervals

TomHsiung — Fri, 05 Jan 2018 16:27:10 GMT

Hello,

I need to do some regression, including multiple linear regression, logistic regression, and Cox-proportional regression. The post estimation confidence intervals of conditional mean and prediction intervals of the response are of interest. I am new to SAS and I use the University Edition. I just don't if I could get these output.

PS: Seems that the University Edition could not do survival analysis.

It seems that the University Edition cannot do survival analysis.

No and No.

Copy and paste this code into SAS UE to see an example of Survival Analysis.

The procedures LIFEREG LIFETEST ICLIFETEST QUANTLIF PHREG and SURVEYPHREG should be available and are the survival regression procedures.

It will help to show the code you are using and at least a description of the specific output you need for each that you are not currently getting and whether you need the results in a data set or only the results window.

You can use OUTPUT or ODS OUTPUT to capture statistics for each procedure.

Just always got this error, I don't know what was wrong.

It’s PROC PHREG and in general PROC not PROedure

I think I need some basic study for SAS programing. I get to read some texts. Thank you.
