如何在R中使用stargazer在同一行中输出多个变量 [英] How to output several variables in the same row using stargazer in R

问题描述

我想从同一行中的多个回归中输出交互项，并将其称为交互".到目前为止，我所拥有的是交互作用术语显示在两个称为交互作用"的不同行中(请参见下面的代码).

I would like to output the interaction terms from several regressions in the same row and call it "Interaction". So far what I have is that the interaction terms show up in two different rows called "Interaction" (see code below).

这里已经问过这个问题，但是我的分数还不够高，不能对其进行评论或评论:

This question has already been asked here, but my score isn't high enough yet to upvote it or comment on it: https://stackoverflow.com/questions/28859569/several-coefficients-in-one-line.

library("stargazer")
stargazer(attitude)
stargazer(attitude, summary=FALSE)
# 2 OLS models with Interactions
linear.1 <- lm(rating ~ complaints + privileges + complaints*privileges
           , data=attitude)
linear.2 <- lm(rating ~ complaints + learning + complaints*learning, data=attitude)
stargazer(linear.1, linear.2, title="Regression Results", type="text", 
      covariate.labels=c("Complaints", "Privileges", "Interaction", "Learning", "Interaction"))

谢谢您的帮助.

推荐答案

我认为这不是本机支持的，因为这不是一个好主意.您正在要求混淆表中数字的含义，这对您的读者没有帮助.

I think this is not natively supported because it is not a good idea. You're asking to obfuscate the meaning of the numbers in your table, which won't help your reader.

现在需要说明的是，您可以通过修改 lm 对象的内容来做到这一点:

That caveat now stated, you can do this by modifying the contents of the lm objects:

# copy objects just for demonstration
m1 <- linear.1
m2 <- linear.2

# see names of coefficients
names(m1$coefficients)
# [1] "(Intercept)"           "complaints"            "privileges"            "complaints:privileges"
names(m2$coefficients)
# [1] "(Intercept)"         "complaints"          "learning"            "complaints:learning"

# replace names
names(m1$coefficients)[names(m1$coefficients) == "complaints:privileges"] <- "interaction"
names(m2$coefficients)[names(m2$coefficients) == "complaints:learning"] <- "interaction"

结果:

> stargazer(m1, m2, title="Regression Results", type="text")
