部分命令如下：
tuples $controlVariables
forvalues i = 1/`ntuples' {
        regress $dependentVariable $independentVariable `tuple`i'', r
        replace bOfIndX = _b[$independentVariable] in `i'
        replace seOfIndX = _se[$independentVariable] in `i'
        replace tOfIndX = bOfIndX / seOfIndX in `i'
        replace degreeOfFreedom = e(df_r) in `i'        
        replace tValue = invttail(degreeOfFreedom, $significance) in `i'
        replace rSq = e(r2) in `i'
        replace controlVariableSet = "`tuple`i''" in `i'
}
