Hi Kate

See the file

blesFromManyFiles.txt

in my web site. This solution assumes that all variables are numeric.

Subject: dropping variables from a data set


Hi:  I have one wave of a data set that has in it all the variables that
were ever asked from all the waves. This particular wave only actually
asked a subset of all those variables, but all the variable names are
included there and have all missing values for all cases. For instance,
church attendance was asked in wave 1, but not in wave 2 (the one I am
using). But there is still a chatten variable in the data set with missing
values. There are too many vars like this to just easily identify. Is
there an easy way to id and drop these variables that would have all
missing values? Thank you.
