AR , Movavg commands
by "Matías F. Rebolledo"
Hello:
1) I'd like to know if, there is any way to solve a ols equation with a
MA second order (q=2), in a similar way as to solve with AR p order
(that's running AR command rather than OLS).
Because I've been using eviews as well, I've noticed that just
introducing either AR(p), or MA(q) as one of the "coefficients" into the
equation, you can solve it very easily. I've ran for the AR test in
gretl and it solved it , but how can I solve a MA(q) process in an equation?
Trying to use ARMA …
[View More]command, I've received a Collineality message. I'm
wondering if there is a way to run only a MA command. I don't understand
so far the use of the MOVAVG command (particularly in the aspect that
it's not centered by default) for solving an equation, which involves a
MA(2) process.
2) Just checking the last mail lists, I've figured that running a ADF
test over Eviews more than once, I've got the same different results of
p-values. But then I noticed that the lags (calculated automaticly by
eviews) were different in each cases, so the p-values were also
different. I don't know the reason neither for this automatic
discrimination.
Heaps of Thanks,
Matías
