Question

How to obtain value of estimated parameters in SAS (proc phreg) ? I have been searching syntax OUTPUT and baseline but they gives only value XBETA ets.

I’m not into statistics, so I’m just guessing what value you mean – here’s an example I think could help you:

ods trace on;
ods output ParameterEstimates=work.my_estimates_dataset;
proc phreg data=sashelp.class;
model age = height;
run;

ods trace off;

This is using SAS Output Delivery System component of SAS/Base.
With ods trace on;, you’ll see references to parts of procedure output in SAS log:

Output Added:
-------------
Name:       ParameterEstimates
Label:      Maximum Likelihood Estimates of Model Parameters
Template:   Stat.Phreg.ParameterEstimates
Path:       Phreg.ParameterEstimates

You can refer to those (usually by Name or Path) and store them in a table with ODS OUTPUT... statement.
Look for SAS ODS user guide for more.
