@Squirtle : Agreed. One can argue in similar way based on Simplex updates.

comment Estimating the transition matrix given the stationary distribution
Thanks Frank. What do you think about mnz's answer? Is the Bayesian estimation really necessary?

comment rank one update for Cholesky factor
By ICF you mean Incomplete Cholesky Factorization? If so, not really. Most of them is based on the idea that, they project the points in a lower dimensional space. I think, in general, the question you're asking, is not trivial.
