How to get the value of estimated parameters in SAS (proc phreg)?

I'm not into statistics, so I'm just guessing what meaning you mean - here's an example I think might help you:

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

ods trace off;

      

        
        
        
      

    

The SAS Output Delivery System SAS / Base component is used. With, ods trace on;

you will see links to parts of the procedure output in the SAS log:

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

      

        
        
        
      

    

You can reference those (usually by name or path) and store them in a table using the operator ODS OUTPUT...

. Look for the SAS ODS user manual for more details.
