In summary, the Tobit model is used when the dependent variable has censored observations, while the logit and probit models areused for binary response variables. The difference between the logit and probit models lies in the distributional assumption of the error term.©...
outcome(varlist)表示结果变量; logit指定使用logit模型进行拟合,默认的是probit模型; neighbor(1)指定按照1:1进行匹配,如果要按照1:3进行匹配,则设定为neighbor(3); radius表示半径匹配 核匹配 (Kernel matching) 其他匹配方法 广义精确匹配(Coarsened Exact Matching) || help cem 局部线性回归匹配 (Local linear ...

if you still believe there is a difference between computing a logit or a probit, then you have to try to regress this: reg y_hatprobit y_hatlogit Look at the R-Squared. The models are practically equals. Feel free to switch between probit and logit whenever you want. The choice should...
probit表示在拟合probit模型后计算倾向得分;默认是logit。 Nocomsup表示样品不应局限于共同支撑的区域。 firststage 表示用OLS估计断点回归。 reducedform使用OLS估计减少的形式效果。 ivregression用工具变量回归估计治疗效果。如果指定了,则要求在treatment(varname)中也指定一个处理变量。

这里ATT的difference是1.41,意思是在其他匹配变量一致的情况下,自变量是1与自变量是0导致的因变量的差异是1.41个单位,这就是我们要求的系数。接下来根据T值确定p值,这里的T值就是个T检验,T值1.96对应的p值是0.05,一半要求大于1.96,具体可查看T检验统计表。不过Note提示了,这个表格的标准误差有两个问题,就是没有...
模型类型可以是regression、logit、logit、probit、oprobit、cloglog、{help logit}、scobit、rologit、clogit、xtlogit、xtprobit和mlogit中的任何一种。其他模型也可能产生输出,但目前这种输出被认为是“实验性的”。 depvar是因变量的名称, key-vars是包含要分解的变量名称的变量列表, ...
Therefore, slightly different models result from adding and subtracting the random residual, corresponding with high-to-low and low-to-high rankings. Thus, the estimated coefficients will differ between the two specifications, though usually not in an important way. You may observe the difference by...
