R- stargazer添加引用类别

Question

我想知道是否有人提出了使用stargazer显示分类变量的引用类别的解决方案？

library(stargazer) 

让我们假设gear和carb是分类变量

mtcars$gear = factor(mtcars$gear)
mtcars$carb = factor(mtcars$carb)

我运行了一个ols

lm1 = lm(disp ~ gear + carb, mtcars)

并对结果进行stargaze。

stargazer(lm1, single.row = TRUE,  omit.table.layout = "sn")

我得到了

但是，我发现自己总是返回到tex文件来定制要获取的引用类别

​

​

基本上，我所做的就是在变量之间添加latex：

gear (ref = 3) &  \\ 
 \-\hspace{0.3cm} gear4 & $-$202.921$^{***}$ (22.477) \\ 

诸若此类。

有没有人知道我是否可以在stargazer函数中添加这种lines？

Answer 1

您可以通过向stargazer提供covariate.labels来获得所需的输出

library(magrittr)
library(stringr) 
library(stargazer) 

covlabels <-
    names(lm1$coefficients)[-1] %>%
    if_else(str_sub(., 1, 4) == "gear" | str_sub(., 1, 4) == "carb", paste("\\-\\hspace{0.3cm}", .), .) %>%
    if_else(str_sub(., 18, 24) == "gear4", paste("gear (ref=3) \\\\", .), .) %>%
    if_else(str_sub(., 18, 24) == "carb2", paste("carb (ref=1) \\\\", .), .) 

stargazer(lm1, single.row = TRUE,  omit.table.layout = "sn", covariate.labels=covlabels)

Answer 2

如果您愿意接受我修改后的策略，那么提取lm1-object中xlevels-lidt-item的名称及其相关的第一层，并用粘贴的字符值替换"(Intercept)值：

baselines = sapply( lm1$xlevels, "[[", 1)
names(lm1$coefficients)[1] = paste0( names(baselines), " = ", baselines, 
                                     collapse="; ")

我现在得到了：

stargazer(lm1, single.row = TRUE,  omit.table.layout = "sn")

我似乎不再有一个正确配置的Latex工具链，可能是由于Apple在上一次OSX“升级”中引入了“增强的安全功能”。
