将三个回归表附加到单独的面板中

Question

考虑以下玩具数据：

input strL Country Population Median_Age Sex_Ratio GDP Trade year
"United States of America" 3999 55 1.01 5000 13.1 2012
"United States of America" 6789 43 1.03 7689 7.6 2013
"United States of America" 9654 39 1.00 7689 4.04 2014
"Afghanistan" 544 24 0.76 457 -0.73 2012
"Afghanistan" 720 19 0.90 465 -0.76 2013
"Afghanistan" 941 17 0.92 498 -0.81 2014
"China" 7546 44 1.01 2000 10.2 2012
"China" 10000 40 0.96 3400 14.3 2013
"China" 12000 38 0.90 5900  16.1 2014
"Canada" 7546 44 1.01 2000 1.2 2012
"Canada" 10000 40 0.96 3400 3.1 2013
"Canada" 12000 38 0.90 5900  8.5 2014
end

我运行不同的回归（使用三个不同的自变量）：

*reg1

local var "GDP Trade"
foreach ii of local var{
qui reg `ii' Population i.year    
est table, b p
outreg2 Population using table, drop(i.year*) bdec(3) sdec(3) nocons tex(nopretty) append
}

*reg2

local var "GDP Trade"
foreach ii of local var{
qui reg `ii' Median_Age i.year    
est table, b p
outreg2 Population using table2, drop(i.year*) bdec(3) sdec(3) nocons tex(nopretty) append
}

*reg3

local var "GDP Trade"
foreach ii of local var{
qui reg `ii' Sex_Ratio i.year    
est table, b p
outreg2 Population using table3, drop(i.year*) bdec(3) sdec(3) nocons tex(nopretty) append
}

我使用append 选项附加要在同一组自变量上回归的不同因变量。因此，我获得了三个不同的表。

当我在LaTeX 中编译时，我希望“合并”这些表，以便它们显示为一个表，具有三个不同的面板，一个在另一个之下。

Table1
Table2
Table3

我可以使用 community-contributed 命令outreg2 的tex(frag) 选项，但这不会给我想要的结果。

Answer 1

这是一个简单的方法，使用 community-contributed 命令esttab:

"United States of America" 9654 39 1.00 7689 4.04 2014

"China" 7546 44 1.01 2000 10.2 2012
"China" 10000 40 0.96 3400 14.3 2013

"Canada" 12000 38 0.90 5900  8.5 2014
end

local var "GDP Trade"
foreach ii of local var{
    regress `ii' Population i.year 
    matrix I = e(b)
    matrix A = nullmat(A) \ I[1,1]
    local namesA `namesA' Population_`ii'
}

matrix rownames A = `namesA'

local var "GDP Trade"
foreach ii of local var{
    regress `ii' Median_Age i.year 
    matrix I = e(b)
    matrix B = nullmat(B) \ I[1,1]
    local namesB `namesB' Median_Age_`ii'
}

matrix rownames B = `namesB'

local var "GDP Trade"
foreach ii of local var{
    regress `ii' Sex_Ratio i.year 
    matrix I = e(b)
    matrix C = nullmat(C) \ I[1,1]
    local namesC `namesC' Sex_Ratio_`ii'
}

matrix rownames C = `namesC'

matrix D = A \ B \ C

结果：

esttab matrix(D), refcat(Population_GDP "Panel 1" ///
                         Median_Age_GDP "Panel 2" ///
                         Sex_Ratio_GDP "Panel 3", nolabel) ///
                         gaps noobs nomtitles ///
                         varwidth(20) ///
                         title(Table 1. Results)

Panel 2

Median_Age_Trade          .429315

Panel 3                          

Sex_Ratio_GDP            18165.85

Sex_Ratio_Trade            27.965
---------------------------------

使用tex 选项：

\begin{table}[htbp]\centering
\caption{Table 1. Results}
\begin{tabular}{l*{1}{c}}

                    &          c1\\

编辑：

这会保留原始格式：

local var "GDP Trade"
foreach ii of local var{
    regress `ii' Population i.year 
    matrix I = e(b)
    matrix A = (nullmat(A) , I[1,1])
    local namesA `namesA' `ii'
}

matrix rownames A = Population
matrix colnames A = `namesA'

local var "GDP Trade"
foreach ii of local var{
    regress `ii' Median_Age i.year 
    matrix I = e(b)
    matrix B = nullmat(B) , I[1,1]
    local namesB `namesB' `ii'
}

matrix rownames B = "Median Age"
matrix colnames B = `namesB'

local var "GDP Trade"
foreach ii of local var{
    regress `ii' Sex_Ratio i.year 
    matrix I = e(b)
    matrix C = nullmat(C) , I[1,1]
    local namesC `namesC' `ii'
}

matrix rownames C = "Sex Ratio"
matrix colnames C = `namesC'

matrix D = A \ B \ C
