Re: System estimation dlog spec - offset 1 period?
Got it. Appears I didn't truncate my sample when executing the fit command. But the question remains why would a value be calculated in 2013 with the code: create a 1991 2015 smpl 1991 2012 series y=rnd smpl 1991 2015 series x1=rnd series x2=rnd equation eq1.ls dlog(y) dlog(x1) dlog(x2) eq1.fit yf s...

Re: System estimation dlog spec - offset 1 period?
Let me rephrase: For an equation of the specification: dlog(y) = c(1)*dlog(x1) + c(2)*dlog(x2) + ... + c(n)*dlog(xn), with annual historical data for the endogenous and exogenous variables from 1990 -2012 (and exogenous variables with values to 2023), I would expect the estimate/static forecast to y...

System estimation dlog spec - offset 1 period?
I'm estimating a system of equations (essentially a pooled regression) with a series of equations of the following form: dlog(y) = c(1)*dlog(x1) + c(2)*dlog(x2) + c(3)*dlog(x3) The results i'm getting appear to be offset by one period. I.e. charting @pchy(y) vs @pchy(yhat) looks off by a period, but...
