i use

global varlist age married dep hh_mem mem
estpost ttest $varlist, by (mig)
    esttab, wide nonumber mtitle("diff.")

I want to get the level of significance at 1% 5% and 10% but stata gives me

t statistics in parentheses
* p<0.05, ** p<0.01, *** p<0.001

How can i change this to reflect the significance i want to show? Thank you for your help in advance.

esttab, note(* 0.10 ** 0.05 *** 0.01)

Hi Chris thank you for your response. I am not sure if t-test is showing the significance at 10% 5% and 1% level because I get the result as below .




I used the following code.

 global varlist age married dep hh_mem mem estpost ttest $varlist, by (mig)    
esttab, wide nonumber mtitle("diff.") note(* 0.10 ** 0.05 *** 0.01)

Hi Naika,

Sorry! I just realized I meant "star". Type the following and it should work:

esttab, star(* 0.10 ** 0.05 *** 0.01)

Hi Chris,

Thank you. That worked. :-)
