Dear All,
The use of "importance" weights seems to increase the number of observations in
the regress command.
E.g.
reg y x
produces an output say with 8 observations
whereas
reg y x [iw=1/weight]
produces an output with 17 observations
Does anybody have an explanation or suggestions for reading?
Best regards
burcin
