Unit Root Checking

[ajoshi]

How can i use the uroot function to simply check for the presence of a unit root within a program? Basically, i want to use uroot in a logical operator, with an if-then function, depending on the presence of a unit root. something along the lines of
If series.uroot () = TRUE then...

something along the lines of:

Code: Select all

freeze(temp) x.uroot !pval = @val(temp(7,5)) if !pval>0.05 then blah endif d temp
