Dear statalist,
I'm running a simple OLS regression but once I use pweight, half of
the observations get dropped. There are no other missing values in the
variables used. I'm simply running
y x1 x2....[pw = weight]
the number of obs used in the regression without the weight is fine,
but once I use the weights the number drops below half. Does anyone
have an idea what's going on? Thanks in advance.
