Dec 22, 2016 at 19:50 comment added HolyMonk Okay great advice. I'll try to do that tomorrow. I'll keep you posted!
Dec 22, 2016 at 19:48 comment added Nate Eldredge I think if you play around with $|S|=3$ for a while you'll be able to find two chains with the same value for $\ell_1$ but different values for $\ell_2$.
Dec 22, 2016 at 19:37 comment added HolyMonk Okay I reconsidered it but yes this "one family of functions $f_m$" is the thing I was hoping for that it would exist. The two dimensional case seemed to hint its existence in my eyes but I don't have any justification for this.
Dec 22, 2016 at 19:28 comment added HolyMonk I will reconsider my question.
Dec 22, 2016 at 19:28 comment added HolyMonk Yes you make a very valid point.
Dec 22, 2016 at 19:25 comment added Nate Eldredge I guess I'm also a little confused by the question. It certainly can't be true that there is a single family of functions $f_m$ that does the job for every possible Markov chain, or even for every possible Markov chain on a given fixed state space $S$. And if you allow the family $f_m$ to depend on the chain, then it is trivially true since you just set $f_m(\ell_1)$ to be whatever $\ell_m$ is for that chain.
Dec 22, 2016 at 19:18 comment added HolyMonk You may assume $S \subseteq \mathbb{R}$
Dec 22, 2016 at 19:17 comment added Nate Eldredge I know how correlation of real-valued random variables is defined, but how do you define the correlation of random variables taking values in an abstract set $S$?
