Question

我想使用语言R来估计嵌套的logit模型。作为我正在使用的＃34; mlogit＆＃34;这类问题的标准包。现在我想估计一个模型，不仅仅是一个阶段。问题如下：

阶段：人们决定是否要迁移到美国。
阶段：对于所有决定迁移的人，他们必须决定他们想要去的美国哪个地区（美国分为6个地区）
阶段：在该地区内，他们决定他们想要居住的地区; urba vs. rural

我已经使用mlogit.data（）转换了我的数据。

data <- mlogit.data(data = usa_canada_uk, choice = "migrant"))

这是＆＃34;数据＆＃34;看起来：

                sex   marst numperhh_cat age_cat   famsize                               nchlt5 labour_code sample                               nchlt10

这是我的想法，我想如何编码，但它不起作用：

mlog <- mlogit(migrant ~ 1  | age + numperhh_cat + sex + famsize + work.prob.home,
             nests = list(home = c("home_country"),
                         foreign = c(region_1 = c("rural", "urban"),
                                     region_2 = c("rural", "urban"),
                                     region_3 = c("rural", "urban"),
                                     region_4 = c("rural", "urban"),
                                     region_5 = c("rural", "urban"),
                                     region_6 = c("rural", "urban"))
                                     ),
           reflevel = "yes",
           weights = perwt,
           data = data)

如您所见，第一阶段的一个巢（决定不迁移=＆＃34; home_country＆＃34;）退化。

如果有人可以帮助我，那就太棒了。

祝福，

克里斯
