我正在尝试使用R中的Stargazer包创建一个回归表。我有几个回归,仅在虚拟变量中有所不同。我希望它报告自变量的系数,常数等,并且如果在回归中包括某些固定效应(即虚拟变量),则说“是”或“否”。这些是我的回归:

iv1 <- ivreg(data=merge1,log(total_units)~log(priceIndex)|log(taxIndex))
iv2 <- ivreg(data=merge1,log(total_units)~log(priceIndex)+factor(fips_state_code)|log(taxIndex)+factor(fips_state_code))
iv4 <- ivreg(data=merge1,log(total_units)~log(priceIndex)+factor(fips_state_code) +factor(year)|log(taxIndex)+factor(fips_state_code) +factor(year))
iv5 <- ivreg(data=merge1,log(total_units)~log(priceIndex)+factor(fips_state_code) +time*factor(fips_state_code)|log(taxIndex)+factor(fips_state_code) +time*factor(fips_state_code))

(顺便提一下,数据框代码在底部。)

如你所见,iv1没有假人。 iv2有状态假人。 iv4有州和年假人。 iv5有状态假人和时间趋势假人。

我不想报告所有这些假人的测试版,而是希望回归能够简单地报告是否包含了每个假人。出于某种原因,我可以使用Stargazer为每个单独的回归工作,因为:

> stargazer(iv1,type="text",
+           omit = c("fips_state_code","year","time"),
+           omit.labels = c("State FE?","Year FE?","State time trend?"))

注意现在所有的假人都被报告为“不”。似乎iv1的使用,没有傻瓜,抛出了Stargazer。我不确定为什么会这样!

所以,我的问题是:如何将组合的Stargazer输出看起来像这样?

答案 0 :(得分:1)

我遇到了与其他模型类型类似的问题,而且固定效果的顺序显得很重要。

如果您只是按顺序翻转模型:

stargazer(iv5,iv4,iv2,iv1,type="text",
       omit = c("fips_state_code","year","time"),
       omit.labels = c("State FE?","Year FE?","State time trend?"))

您获得了正确的输出:

答案 1 :(得分:0)

我根本不想打印出我的回归中使用的所有虚拟对象,这个问题困扰超过3小时,而且在这里找到它真是令人惊讶。

我尝试了弗洛里安建议的那种方法,实际上,在我的情况下,回归中出现的固定效果顺序并不重要,我在这里运行plm,下面是我的观星代码:

stargazer(cluster.matched.fixed.7,cluster.matched.fixed.2,cluster.matched.fixed.3,cluster.matched.fixed.4,
          cluster.matched.fixed.5,cluster.matched.fixed.6,cluster.matched.fixed.1,title="Matched sample regression DID results",
            omit.stat = c("f"),covariate.labels=c("D","D1","D2","log(ROA)","log(totalasset)","log(sales)",
                             "log(GM)","log(Export)","log(Leverage)"),omit = c("year"),omit.labels = c("Year FE?"))

其中回归7没有固定的效果,结果是正确的。 对我来说更有趣的是你在哪里找到omit =

c("fips_state_code","year","time"),
       omit.labels = c("State FE?","Year FE?","State time trend?")
&#34> stargazer&#34;中的参数,我从R-cran打印出来的文件,但没有类似的东西。
