This method has been seriously questioned and gives very poor answers generally.  A true p-value may be reported anywhere from 0.01 to0.15 when it should be 0.05.  I strongly urge it not be used.

Hello to All,
Once again, thanks to Kit Baum, a new version of -carryforward- is
available on SSC.
This upgrade adds the -if- and -in- qualifiers.
Actually, the upgrade was written a long time ago, but never got
uploaded until now. Sorry, if that was my fault.

-carryforward- carries values from one observation to the next,
filling in missing values.

-ssc install carryforward-
