Ok.Prof. We can get the CUSUM or CUSUMSQ plot via the GUI. But my intention/ requirement is to graph CUSUM or CUSUMSQ via code to add in a script developed for Asymmetric Cointegration and Dynamic Multiplier in a Nonlinear Framework . Almost all the available studies on ARDL and NARDL used them in ARDL and NARDL Models Using stata or Eviews or R prog . Hence, I want to incorporate the CUSUM or
--plot command and expect your --plot command shortly.
Once again thanking you for your immediate response.
Best regards.
Dhanasekaran. K
