Question

运行回归后，我想在Excel电子表格中保存输出（变量名称，系数，标准误差和P值）。当我尝试这样做时，我只得到系数。这是我的尝试。请注意我使用的是无法访问互联网的计算机，因此无法使用外部库。

local regressors x1 x2 x3
logit y `regressors'
putexcel set output_table.xlsx, replace
putexcel A1 = matrix(e(b))

Answer 1

e(b)矩阵仅包含系数，而矩阵r(table)具有所有必需的信息。

使用Stata的lbw玩具数据集考虑以下玩具示例：

webuse lbw, clear
logit low age lwt i.race smoke

matrix list e(b)

e(b)[1,7]
           low:        low:        low:        low:        low:        low:        low:

matrix list r(table)

r(table)[9,7]
               low:        low:        low:        low:        low:        low:        low:

以下内容将在output_table Excel电子表格中写入所有内容，包括变量名称：

matrix A = r(table)
matrix A = A[1..2,1...] \ A[4,1...]
matrix coleq A = ""

matrix list A

A[3,7]
                                        1b.          2.          3.

putexcel set output_table.xlsx, replace
putexcel A1 = matrix(A), names
