Propensity Score Matching Algorithms

Postby gford » Thu Aug 06, 2009 1:05 pm

If you are looking for Propensity Score matching algorithms, see the paper at this link: http://www-wds.worldbank.org/servlet/WD ... ev0pdf.pdf. I have not implemented them yet, but plan to.

Hi, I'm trying to implement this program but I have an error that says: 'missing values in @LOGL series at current coefficients at observations 2'. I know there are missing values in my data and i was wondering whether there was a way to get eviews to remove them as it does not seem to have done it automatically in this case?

Thanks

Set the sample so that the missings are excluded prior to estimation, as in

smpl if y<>na

If there are a number of series with NAs, put them in a group, say GRP1 then set the sample as

smpl if @rnas(grp1)=0

which sees whether there are missings in any of the series for each observation.
