Dear Tom,

When we use Errors instructions to compute the VDCs we get a standard error in output, is it the standard error for the residuals from the VAR or for point estimates of the VDCs?

Standard error of forecast (computed at the point estimates).

Dear Tom,

I am getting the following error:

## EQ4. Equation %M(AICLAG,1) Has At Least One Undefined or NA Coefficient

## EQ4. Equation %M(AICLAG,2) Has At Least One Undefined or NA Coefficient

## EQ4. Equation %M(AICLAG,3) Has At Least One Undefined or NA Coefficient

## EQ4. Equation %M(AICLAG,4) Has At Least One Undefined or NA Coefficient

when i am trying to modify equations 2 to 5 of the system previously estimated. Can you please help me explain what is the problem, it does work properly for the first equation.

Regards,

Ateeb

So this is the situation:

I have x1, x2, x3, x4 and x5. x4 and x5 are stationary.

x1, x2 and x3 are cointegrated of order 1. so i use Engle-Granger 2 step estimation.

I form e11 as my equilibrium error.

I run system with all stationary variables with x1, x2 and x3 as stationary. Then i modify the system by replacing x4 and x5 by themselves as they are stationary in levels and do no differences, but x1, x2 and x3 in levels with differencing. so it is a vecm with everything specified properly. However, it works for equation 1 and as soon as i do that for second one it does not.

Furthermore, the system has 6 lags as picked up by AIC but i can see x1 comes with 7 lags as a result of first modification (i mean coefficients) and same is the case with x2 and x3. whereas x4 and x5 comes with 6 lags.

So I dont know whats going on. furthermore, i could not find %M in manual, user guide or reference manual. What does it show?

The LAGS option in CATS (and in @JOHMLE and pretty much all of the cointegration procedures) are the number of augmenting lags which is one less than the number of lags in the expanded model.

Thank you I got the idea!
