Question

我想从同一行中的几个回归中输出交互项，并将其称为“＃34;交互”＃34;。到目前为止，我所拥有的是交互术语出现在两个不同的行中，称为＆＃34; Interaction＆＃34; （见下面的代码）。

此问题已在此处提出，但我的分数还不够高，尚未对其进行评论或评论：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"))

感谢您的帮助。

Answer 1

我认为这不是本机支持的，因为它不是一个好主意。您要求对表格中数字的含义进行模糊处理，这无法帮助您的读者。

现在说明了这一点，你可以通过修改lm个对象的内容来实现这个目的：

# 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")

Answer 2

以下回应：

reg ~ felm(....)
rownames(reg$coefficients)[rownames(reg$coefficients)=='oldname']<-'newname'
rownames(reg$beta)[rownames(reg$beta)=='oldname']<-'newname'

似乎适用于大多数情况。

尽管我有时会遇到问题。当felm与IV一起使用时，这是必需的。区分带IV和不带IV的变量虽然很好，但与其他模型相比，这些表会很麻烦！这样的语法将很有帮助。

Answer 3

万一有人想知道，我出于felm软件包的其他目的而需要它。为此，需要以下代码：

reg ~ felm(....)
rownames(reg$coefficients)[rownames(reg$coefficients)=='oldname']<-'newname'
rownames(reg$beta)[rownames(reg$beta)=='oldname']<-'newname'
