stata--二维表

什么是二维表（twoway tables）

用来统计分类变量（categories）的频数的

tab命令

二维表基础命令，统计一个变量叫一维表，两个变量叫二维表。
tab后跟的第一个变量可以认为是“垂直变量”，第二个变量可以认为是“水平变量”。

sysuse nlsw88, clear
tab union //一维表
tab union sex //二维表

二维表输出命令tabout

tabout race south collgrad using table39.docx, ///
replace style(docx) font(bold) c(freq row col) ///
f(0c 1 1) layout(cb) landscape title(Table 39: ///
Example of rotation with docx output style) ///
fn(nlsw88.dta) open

**c(freq col) ** is the contents option, which determines the cell
contents: frequencies and column percentages

f(0c 1) is the format option and sets the cell numbers as zero decimal points with commas for the frequencies and one decimal point for the column percentages

font(bold) turns on bold formatting for the variable labels and the
second row of the heading;

twidth(11) sets the width of the table to 11 centimetres

title(Table 1 etc) is placed above the table

fn(Source etc) is a footnote placed below the table
