Time Series: A Data Analysis Approach Using R by R.H. Shumway and D.S.
Stoffer. Chapman & Hall, 2019.
There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call T i M e S e R i e S.

You're travelling through another dimension, a dimension not only of sight and sound but of mind; a journey into a wondrous land whose boundaries are that of imagination. That's the signpost up ahead - your next stop ...

You unlock this door with the key of imagination.
Beyond it is another dimension... a dimension of sound,
a dimension of sight, a dimension of mind.
You're moving into a land of both shadow and substance,
of things and ideas. You've just crossed over into...

We still get many requests for the tech report corresponding to
this paper. Unfortunately, the
tech reports are long gone (believe it or not, in those days people
typed their papers using an
IBM selectric typewriter with little balls
that had to be changed for math symbols). Fortunately, the details of the proofs
(in more depth than was
given in the tech report) are
presented in our text
in Sections 6.2 to 6.4.
