I'd appreciate assistance in locating a copy of Partick Royston's 'ptrend' ado file.
I know that this was sent to the list back in 1996 and I see that Fred Wolfe kindly replied - with a copy - to a query last year....

ptrend has one simple attraction compared with 'opartchi' - it presents the regression fit simultaneously with the test for trend and as I'm testing upwards of 1,000 different sets of observations, this facility is convenient.
Many thanks,
