To apply a statistical model to control for the remaining imbalance, we simply add variables to the regression command. For example: 如果选择了精确匹配(即,不进行粗化),则该程序按原样是合适的。在其他情况下,通过一些粗化,匹配数据中仍然存在一些不平衡。剩余的不平衡受到粗化水平的严格限制,这可以通过粗化...
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, z-vars是包含感兴趣的控制变量名...
Stata 回归简介 线性回归的命令有: regressyx1x2x3 以 y 为被解释变量, x2, 为解释变量做回归; ( x1, x3 regress 后第一个变量为被解释变量) regressyx1x2x3,robust(regressionwithrobuststandarderrors) regressyx1x2x3[aweight=w](WLS,以变量 w 为权重) regyx1x2x3,level(99)返回回归报告中 99%的...
This should mean that my instruments are not correlated with the error of the main regression and therefore they are valid. Now, I want to add an other exogenous regressor in the main regression, and for this reason I write: >ivregress 2sls dep (endo endoX exo = instrument1 instrument2 ...

Regression问题的常规步骤为: 寻找h函数(即hypothesis); 构造J函数(损失函数); 想办法使得J函数最小并求得回归参数(θ) 构造预测函数h Logistic回归虽然名字里带“回归”,但是它实际上是一种分类方法,主要用于两分类问题(即输出只有两种,分别代表两个类别),所以利用了Logistic函数(或称为Sigmoid函数),函数形式为: ...

Below we use the mlogit command to estimate a multinomial logistic regression model. The i. before ses indicates that ses is a indicator variable (i.e., categorical variable), and that it should be included in the model. We have also used the option “base” to indicate the category we ...
