COXREG

COXREG 可在 自訂表格及進階統計量中使用。

COXREG 將 Cox 比例風險迴歸套用至存活時間分析-即事件發生之前的時間長度。

COXREG VARIABLES = survival varname [WITH varlist]
    / STATUS = varname [EVENT] (vallist) [LOST (vallist)]
   [/STRATA  = varname]
   [/CATEGORICAL = varname]
   [/CONTRAST (varname) = {INDICATOR (refcat)}
                          {DEVIATION (refcat)}]
                          {SIMPLE (refcat)   }
                          {DIFFERENCE        }
                          {HELMERT           }
                          {REPEATED          }
                          {POLYNOMIAL(metric)}
                          {SPECIAL (matrix)  }

   [/METHOD = {ENTER**      }   [{varlist}]]
              {BSTEP [{COND}]}    {ALL    }
                      {LR  }
                      {WALD}
              {FSTEP [{COND}]} 
                      {LR  }
                      {WALD}

   [/MISSING = {EXCLUDE**}]
               {INCLUDE  }

   [/PRINT = [{DEFAULT**}]  [CI ({95})]]
              {SUMMARY  }        {n }
              {BASELINE }
              {CORR     }
              {ALL      }

   [/CRITERIA = [{BCON}({1E-4**})]   [LCON({1E-5**})]
                 {PCON} { n    }           { n    }
                [ITERATE({20**})]
                         { n  }
                [PIN({0.05**})]      [POUT({0.1**})]]
                     { n    }              { n   }

   [/PLOT = [NONE**] [SURVIVAL] [HAZARD] [LML] [OMS]]
   [/PATTERN = [varname(value)...] [BY varname]]
   [/OUTFILE = [COEFF('savfile' | 'dataset')] [TABLE('savfile' | 'dataset')]
               [PARAMETER('file')]]
   [/SAVE = tempvar [(newvarname)],tempvar ...]
   [/EXTERNAL]

* * 如果省略次指令或關鍵字，則為預設值。

由 COXREG 建立的臨時變數如下:

• SURVIVAL
• 標準誤
• 風險(H)
• RESID
• LML
• DFBETA
• PRESID
• XBeta

此指令會讀取作用中資料集，並導致執行任何擱置指令。 如需相關資訊，請參閱主題 指令順序 。

可從「 Cox 迴歸分析 」對話框產生 COXREG 指令的語法。
