Subject: generating variable with previous values [was: RE: st: Wald test
limit?]
Please read the FAQ on using informative titles, on not replying to
other threads and on deleting irrelevant material.
You don't say what your difficulty is. But perhaps this example will
help:
. bysort mother_id (B_order) : gen prev_infd = infd[_n-1]
