下面涉及社区贡献命令esttab
(基于来自estout
的help file的代码)的解决方案提供了一种显示同一行中不同回归的系数的方法。
但是,排序是出乎意料的。我怎样才能解决这个问题?
首先,我定义了一个程序appendmodels
:
capt prog drop appendmodels
program appendmodels, eclass
// using first equation of model
syntax namelist
tempname b V tmp
foreach name of local namelist {
qui est restore `name'
mat `tmp' = e(b)
local eq1: coleq `tmp'
gettoken eq1 : eq1
mat `tmp' = `tmp'[1,"`eq1':"]
local cons = colnumb(`tmp',"_cons")
if `cons'<. & `cons'>1 {
mat `tmp' = `tmp'[1,1..`cons'-1]
}
mat `b' = nullmat(`b') , `tmp'
mat `tmp' = e(V)
mat `tmp' = `tmp'["`eq1':","`eq1':"]
if `cons'<. & `cons'>1 {
mat `tmp' = `tmp'[1..`cons'-1,1..`cons'-1]
}
capt confirm matrix `V'
if _rc {
mat `V' = `tmp'
}
else {
mat `V' = ///
( `V' , J(rowsof(`V'),colsof(`tmp'),0) ) \ ///
( J(rowsof(`tmp'),colsof(`V'),0) , `tmp' )
}
}
local names: colfullnames `b'
mat coln `V' = `names'
mat rown `V' = `names'
eret post `b' `V'
eret local cmd "whatever"
end
然后我运行回归并使用该程序将这些回归的结果合并为一个:
eststo clear
sysuse auto, clear
eststo b1: regress price weight
eststo b2: regress price mpg
eststo b3: regress price foreign
eststo bivar: appendmodels b1 b2 b3
然后我转置它们:
esttab b1 b2 b3 bivar, se nostar noconstant
matrix C = r(coefs)
eststo clear
local rnames : rownames C
local models : coleq C
local models : list uniq models
local i 0
foreach name of local rnames {
local ++i
local j 0
capture matrix drop b
capture matrix drop se
foreach model of local models {
local ++j
matrix tmp = C[`i', 2*`j'-1]
if tmp[1,1]<. {
matrix colnames tmp = `model'
matrix b = nullmat(b), tmp
matrix tmp[1,1] = C[`i', 2*`j']
matrix se = nullmat(se), tmp
}
}
ereturn post b
quietly estadd matrix se
eststo `name'
}
esttab, se mtitle noobs
结果:
------------------------------------------------------------
(1) (2) (3)
weight mpg foreign
------------------------------------------------------------
b1 2.044***
(0.377)
bivar 2.044*** -238.9*** 312.3
(0.377) (53.08) (754.4)
b2 -238.9***
(53.08)
b3 312.3
(754.4)
------------------------------------------------------------
显然,顺序已经改变:而不是b1
,b2
,b3
,bivar
,它是b1
,bivar
,b2
,b3
。
如何改变排序为qazxsw poi,qazxsw poi,qazxsw poi,qazxsw poi?
只需使用b1
的b2
选项:
b3
