Hello everyone,

I am trying to do the following : -

I have a variable r. I want to create a variable m=min( r, r[_n-1],
... ,r[_n-9])

I guess I can use a while loop to do this but that is quite slow. An
alternative would be to define r0=r,r1=r[_n-1],..,r9=r[_n-9]
and then say m=rmin ( r0 r1 ... r9).

My question is that is there a built in way in stata to do this ? like
say by using egen ?

Thank you all for your time and effort.

Ashim. : )
