Hi,

I am trying to format a series of regression tables with estout/esttab. My regressions all have the same sample size. Is there a way to include the sample size in the table notes / footer instead of having the same information repeated for all models?

Is there a way to use a variable like the sample size in esttab, addnotes or estout, notes?

See reproducible example below:

Code:
. sysuse auto
(1978 Automobile Data)

. eststo: quietly regress price weight mpg
(est1 stored)

. eststo: quietly regress price weight mpg foreign
(est2 stored)

. esttab

N                      74              74   <- This is what I wanted to move to the table footer

t statistics in parentheses

This is what I wanted:

                    price           price
