a nice description can be found in
Wolfe, R and Hanley, J (1/8/2002), "If we're so different, why do we
keep overlapping? When 1 plus 1 doesn't make 2", _Canadian Medical
Association Journal_, 166: 65-66

Not quite. If they don't overlap, then yes, they are
different; but if they do overlap, the two intercepts
may still be significantly different at an alpha of 5%.

See whether their confidence intervals overlap...

Dear Stata List,
I have computed two linear regressions and would like to compare
the computed intercepts statistically. Is there a command or
command process that can achieve this? Thank you for your assistance.
