Stata users, 
 I have a small problem within a loop. I have estimated a variable using the command dfgls
dfgls variable1
I saved the lag order at the minimum of the MAIC into a scalar
scalar x=r(maiclag)
* and I saved all the statistics into a matrix
matrix y=r(results) 
Now I want to be able to retrieve the DFGLS statistic from matrix y if the value of the lag k within that matrix equals the value of the scalar x and call both into a variable that I can see within the data editor
I am not conversent with calling matrix values in stata. 
Any sugestion please?
many thanks
