Plot of Predicted Survival Curves (for Version 6.0):  (J.M.Garrett 11/17/99)

   ^stcoxplt^ [^if^ exp]^, x^var^(^xvar^)^ [^adj^ust^(^covlist^) nolo^g ^nosh^ow graph_options]


^stcoxplt^ plots the predicted survival curves estimated from the Cox
    Proportional Hazards model by categories of a nominal x variable (one
    survivor function); dummy variables are created from the x variable
    and renamed x2, x3, etc., with the lowest category the reference
    group; covariates are centered by default based on the observations
    used in the model, or can be set to specified values; optionally, the
    model is printed. You must have ^stset^ your data before using this
    command; see help @stset@.


Options required
----------------
  ^x^var^(^xvar^)^ -- nominal x variable


Options allowed
---------------    

  ^adj^ust^(^covlist^)^ -- any covariates (if none specified, unadjusted estimates
                     reported); Covariates are set to their mean, based on
                     observations used in the analysis, or can be set to user
                     specified values (e.g., age=50 gender=1).

Examples 
--------

 . ^stset weeks, failure(relapse)^
 . ^stcoxplt, xvar(trtment) adj(wbcc) c(ll) model^

     Plots the survival curves for weeks to relapse for leukemia patients by
     categories of treatment adjusted for white blood cell count; connects
     curves with lines and default symbols; displays model


 . ^stset days, failure(died)^
 . ^stcoxplt, xvar(celltype) adj(trt=1 severity) c(JJJJ) s(iiii)^ 

     Plots the survival curves for days until death for lung cancer patients
     by cancer cell type, adjusted for treatment=1 and the mean severity score;
     connects curves with step functions and no symbols; model not printed
