replace x = x * sign(y)
Stata's documentation of functions is ultra-dry. At
some point one just has to scan the list and see
what there is.
At the Stata Journal we are open to publishing tutorial-type
articles on the more exciting functions, but with
-sign()- I would be pushed to do more than restate the
definition.
