Subject: Re: st: deleting observations
Once more I would like to get your help on deleting
observations. When I run equation 1 below after the
command (bys hhn: drop if _N==1) the minimum number of
observation per group (household (hhn) is two.
However, When I run equation 2 below for the
sub-sample of observations using indicator variable
(sterrace ==1) after the command (bys hhn: drop if
_N==1) the minimum number of observation per group is
one. I was expecting the minimum observation per group
to be more than one. I am not clear why this is
happening. I appreciate any help on this.
