Also it gives problem for eigen values table and graph with few values outside eigen circle.So I have to stick to this lag length. Do you have any idea to solve this issue in STATA.
In Stata (not STATA!) this evidence from the eigensystem suggests that some of your variables fail to satisfy the requirements for dynamic stability of the VAR, possibly because they are unit root (I(1)) processes. It is difficult to test them for stationarity given only 30 obs. but if other research using these variables has focused on their differences rather than their levels, I would heed it.
