st: Patrick Royston's ptrend

[Alan Kelly <akelly@tcd.ie>]

Hi,
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,
Alan
