covariate plot syntax in coxreg

[parisec]

 

 

Hi all,

 

I'm running cox regression. A neat feature is the ability to plot the survival curves for different levels of covariates. So, rather than having to use the mean age in the plot, I can tell it to plot the curve for age 30 etc. I have done this through GUI and pasted the syntax. Now i would like to rerun the analysis for age 40 but the sytax for the plots is just: /PLOT SURVIVAL without showing the age  that I selected through the GUI.

 

Anyone know if this can be done through syntax or do i have to keep going back to the GUI and changing the level?

 

Thanks

Carol

Please post the syntax generated by the GUI?
When I go in and paste syntax I get something like:
COXREG
  time_var  /STATUS=oops(1)
  /PATTERN age(30)
  /METHOD=ENTER z
  /PLOT SURVIVAL
  /CRITERIA=PIN(.05) POUT(.10) ITERATE(20) .
Perhaps /PATTERN age(30) might have something to do with controlling the PLOT ;-)

aggh! i guess it's time for coffee. i had some strange idea that this should show up under  /PLOT since this is where i changed this in the GUI.

sorry
