Re: st: Re: Retrieving a master dataset after merging
Also assuming that it's a one-to-one merge - if not the number of
observations would have increased. Also assuming that the OP has
specified the merge correctly - again the number of observations might
have increased if there's more than one merge in the -using- data.
I think it's best to start from scratch.
