{pstd}
{cmd:lincomestadd} is just {cmd:lincom}, except that it also saves the output to e() stored results, instead of just r(). It does this by calling {cmd:estadd}.

{pstd}
It saves into e() the formatted strings

{p2colset 9 25 25 1}{...}
{p2col:e({it:prefix}b)}r(b){p_end}
{p2col:e({it:prefix}se)}r(se){p_end}
{p2col:e({it:prefix}df)}r(df){p_end}
{p2col:e({it:prefix}t)}associated t-statistic{p_end}

{pstd}
where the strings are formatted according to {format(%fmt)}}, with default %04.3f. It also includes significance stars on e({it:prefix}b) unless the option {opt nostars} is specified. Parentheses are placed around the standard error.

{pstd}
It also saves all of the non-formatted results as numeric values in e({it:prefix}stat_num).

{pstd}
The formatted strings are particularly useful when making tables with e()-results.

This command requires the estadd package ({cmd:ssc install estadd}).
