comment A question on a compact space
Too tired right now to finish this right now, but here is what I had: If a discrete subset is closed, then it has a finite subcover (the singletons of a discrete set form a basis of it, so the singletons are the finite cover). Therefore, every discrete subset of the space is finite...

comment How to deal with non random data in statistical analysis?
Without having looked at your data, my hunch is there is a strong likelihood there is a random component. And yes, there are a number of model selection techniques you can use to parameterize a sufficient time-series model, ARMA may be appropriate for what you're doing.

I agree, using this in a bivariate transformation would be appropriate.

comment Eigenvalue problem: Prove that all of the eigenvalues of $A$ are $1$.
RE: (1), I went back and read the comments, and that's a good question - what are some of the other ways to arrive at such a result? RE: (2), matrix elements can be either 0 or 1. If a diagonal element is zero, then the matrix is singular and the determinant is therefore also zero, thus all eigenvalues cannot be positive. RE: (3), that paper definitely spells out a more direct route, thanks for sharing it.
