r - 在 stargazer 表中显示自由度

Question

在使用 Sweave 和 R 构建文档时，我使用了 stargazer 库来制作表格。

当使用 stargazer 时，是否有一种机制可以显示与 glm 构建的模型的残差相关联的自由度？

最少的代码:

library(stargazer)
set.seed(1234)
data <- data.frame(x=1:10)
data$y <- data$x + rnorm(10, 0, 0.2)
model <- glm(y~x, data=data, family=gaussian)
summary(model)
stargazer(model,title="A test", align=T,label="Tab:test",style="all2")

生成的 stargazer 表将包含观测值、对数似然、AIC、残差和零偏差，但没有 d.f。我可以锻炼 d.f.但本来以为这可以直接显示。另见:

更新 #1:

感谢 Marek 的回复。为了其他遇到此问题的人的利益，以下是让您形成解决方法的过程:

1. 从 http://cran.r-project.org/src/contrib/Archive/stargazer/ 获取版本 4.0(不是 4.5 - 我会回来讨论这个)
2. 在 R 下的包目录结构中，按照以下答案中的说明编辑“stargazer-internal.R”。
3. 确保库未加载到您的 R session 中
4. 确保您已删除任何现有的 stargazer 库
5. 安装 stargazer 包的编辑版本。
6. 在 R 中重新加载库并照常编译。

命令如下:

detach("package:stargazer", unload=TRUE)
remove.packages("stargazer")

从命令行:

R CMD INSTALL -l <path to library directory> stargazer

最后(假设您手头有几个模型)，

library(stargazer)
stargazer(model6,model7,model8, title="Logistic model summary",align=T,label="Tab:logmod1",  font.size="footnotesize", style="all2")

结果:

回到我根据 4.5 代码实现解决方法时遇到的错误。当我从 mac 二进制文件(版本 4.5.1)(http://cran.r-project.org/web/packages/stargazer/index.html)安装并尝试使用 stargazer 时，我实际上遇到了同样的错误，见下文。

Marek，为了您的引用，我会将结果 traceback() 通过电子邮件发送给您。干杯。

Answer 1

观星者作者在这里。看起来包的默认设置是不输出残差和零偏差的自由度。我会考虑在未来的版本中更改默认值。

作为目前的快速修复，您可能希望使用源包(来自 CRAN)，并修改 stargazer-internal.R 中的函数 .adjust.settings.style 以包含以下内容:

   if (style == "all") {
      .format.table.parts <<- c("=!","dependent variable label","dependent variables","models","columns","numbers","-","coefficients","-","omit","-","additional","N","R-squared","adjusted R-squared","max R-squared","log likelihood","sigma2","theta(se)*(p)", "SER(df)","F statistic(df)*(p)","chi2(df)*(p)","Wald(df)*(p)","LR(df)*(p)","logrank(df)*(p)","AIC","BIC","UBRE","rho(se)*(p)","Mills(se)*(p)","residual deviance(df)*","null deviance(df)*","=!","notes")  
      .format.coefficient.table.parts <<- c("variable name","coefficient*","standard error","t-stat","p-value")  
    }

    else if (style == "all2") {
      .format.table.parts <<- c("=!","dependent variable label","dependent variables","models","columns","numbers","-","coefficients","-","omit","-","additional","N","R-squared","adjusted R-squared","max R-squared","log likelihood","sigma2","theta(se)*(p)", "SER(df)","F statistic(df)*(p)","chi2(df)*(p)","Wald(df)*(p)","LR(df)*(p)","logrank(df)*(p)","AIC","BIC","UBRE","rho(se)*(p)","Mills(se)*(p)","residual deviance(df)*","null deviance(df)*","=!","notes")  
      .format.coefficient.table.parts <<- c("variable name","coefficient*","standard error")  
    }

请注意，这里唯一的变化是我在“剩余偏差”和“零偏差”中添加了“(df)*”。
