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). ^m^odel -- display model as well as plot ^nolo^g ^nosh^ow ^xla^bel ^s^ymbol ^c^onnect titles 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 Also see -------- Manual: ^[R] st sts graph^ ^[R] st stcox^ On-line: help for @st@, @sts@
