i have 2 variables inflation and trade openness(OT) in log form and I(1). i need to check casuality between the 2 with toda and yamamoto test and 3 lags ..kindly guide how to do this in eviews..i write the following equation in estimate equation window :
lninf c lninf(-1) lnot1(-1) lninf(-2) lnot1(-2) lninf(-3) lnot1(-3) which shows following results:

Estimation Equation:
=====================
LNINF = C(1) + C(2)*LNINF(-1) + C(3)*LNOT1(-1) + C(4)*LNINF(-2) + C(5)*LNOT1(-2) + C(6)*LNINF(-3) + C(7)*LNOT1(-3)

then i check for cofefficent rstriction from view menu and write c(1)=c(2)=c(3)=c(4)=c(5)=c(6)=c(7)=0 and get following chi square results
value(prob.) = 12733.14 (0.0000)with 7 d.f..

i get this type of result for all the equations i have .. o prob and d.f comes to be equal to numer of c()
..kindly guide is it the right ans if not plz suggest the right way.
thanks

thanku so much for this article..i have already read this but i dont knoww how to conduct all this in eviews..what to write to check max lag length selection criteria and to check wald restriction in eviews..plz help n guide me.thanku
