Question

您好我想使用 table 命令创建一个三向表。但是，我想要百分比而不是频率。

table  var mcdstr year  ///
if inlist(year,1900,1930) &  inlist(mcdstr,"BRONX","BROOKLYN","MANHATTAN","QUEENS","RICHMOND")

据我所知， table 命令没有内置频率功能。因此，我使用了具有内置百分比命令的 tabout 命令。我用了这个命令

tabout lit mcdstr year if ///
inlist(year,1910,1930) &  inlist(mcdstr,"BRONX","BROOKLYN","MANHATTAN","QUEENS","RICHMOND")  using table1.text, ///
cells(freq col cum) format(0 1) clab(No. Col_% Cum_%)

但是，此命令不会创建三向表。我想知道是否可以使用 table 命令计算百分比，或者使用 tabout 创建一个三向表。

最简单的方法是使用社区贡献的命令tab3way：

ssc install tab3way

使用Stata的auto玩具数据集的示例可以在下面找到：

sysuse auto, clear

tab3way headroom rep78 foreign

Table entries are cell frequencies

Headroom  | --------- Domestic ---------    ---------- Foreign ---------
(in.)     |    1     2     3     4     5       1     2     3     4     5

        2 |    1     3     8           2                   2     6     5
        3 |          1    13     3                         1     2     4
        4 |          3     6     5

要添加百分比：

tab3way headroom rep78 foreign, cellpct

对于没有频率的百分比：

tab3way headroom rep78 foreign, cellpct nofreq

Table entries are cell percentages
