outreg2里自己设定下就好了。。

谢谢哈 搞定了

你好，跟你有同样的问题，能不能教我下要怎么设定啊？十分感谢~

outreg2的帮助文件上有说明。
alpha(numlist) specifies the levels of significance, separated by comma from the most significant
        to the least signficiant. Example: alpha(0.001, 0.01, 0.05). Up to 3 are automatically assigned
        asterisks. If more than 3 levels are defined, then the symbols must be specified with
        symbol(text).
symbol(text) specifies symbols for the levels of significance from the most significant to the
        least significant, the default symbol(***, **, *).
        They will assigned the significance levels of 0.01, 0.05, and 0.10 automatically in
        that order. If more than 3 symbols are assigned, then the same number of levels of
        significance must be specified using alpha.

如果您懒地看英文，或看了还是不太清楚，
以下是范例，请参考！
假设您无聊到用四种显著水准【即0.001  0.01 0.05 0.1】并且是四种符号【# * + $】
当然随您高兴，您可以设计更多样化，Stata很贴心的！

set seed 12345
set obs 10000
drawnorm u1 u2 u3
gen x1=uniform()
gen y1=0.7*x1+u1
gen x2=uniform()
gen y2=0.5*x1+0.7*x2+u2
gen x3=uniform()
gen y3=0.3*x1+0.5*x2+0.3*x3+u3

reg y1 x1
estimates store a1

reg y2 x1 x2
estimates store a2

reg y3 x1 x2 x3
estimates store a3

outreg2 [a1 a2 a3] using d:\testout3, word excel replace alpha(0.001, 0.01, 0.05,0.1) symbol(#, *, +,$)

灰常感谢！！！！！！
