I got the code for how to do regression without an intercept out of the back
of my book and the next part of the homework asks me to do it with an
intercept. The problem is, Q1 disappears whenever I try. Here is my code:
Without the intercept:
load("tsa3.rda")
>
> Q=factor(rep(1:4,21))
> reg=l
thanks.

Hi guys,
I'm trying to do the autocovariance of a moving average but it's giving me
errors. Here is my code:
> w=rnorm(500,0,1)
> v=filter(w, sides=2, rep(1/3,3))
> acf(w, lag.max=20) <=that printed out a nice graph.
> acf(v, lag.max=20)
Error in na.fail.default(as.ts(x)) : missing values in
3 matches
