| Jul 28, 2014 at 23:45 | comment | added | math-Student | @AnthonyQuas, yes thats true. You can interpret this double Markov relation in a more compact way: for three random variables $X$, $Y$ and $W$ we have $\Pr(X=x|W=w, Y=y)=\Pr(X=x|Y=y)=\Pr(X=x|W=w)$. | |
| Jul 28, 2014 at 22:53 | comment | added | Anthony Quas | Do you mean that you have three random variables $X$,$Y$ and $W$ all defined on the same probability space, such that $\mathbb P(Y=y|X=x,W=w)=\mathbb P(Y=y|W=w)$ and $\mathbb P(W=w|X=x,Y=y)=\mathbb P(W=w|Y=y)$? | |

| Jul 28, 2014 at 22:51 | comment | added | math-Student | @RW, the problem asks for the existence of some functions $f$ and $g$ with domains $\mathcal{X}$ and $\mathcal{W}$ which are the alphabets over which two random variables $X$ and $W$ are defined. The ranges can be anything. | |
| Jul 28, 2014 at 22:10 | comment | added | guest | does this mean you can have markov relation x->w->y->w->y->w->...? | |
