Simple question: unless I missed it, it seems that there is not an equivalent of cdemean for series (and hence lists), i.e. a command centering on the mean a given series or all the series included in a list. In other words, something like diff(list) which computes their first differences. Sometimes it could come handy.
bye, and thanks as usual!
