Dear D. Labes,

❝ [...] BTW could not find any hint up to now what this really means: General positive-definite, Log-Cholesky parametrization. Questions for that are always answered: Buy the book of Pinheiro/Bates "Mixed-Effects Models in S and S-PLUS", Springer (2000), there it is described.

I have it in my shelf, but

too stupid to understand >90% of it's contents
too short of time to dig into it
but maybe this is helpful to initiates? On page 59 you find the only mentioning of 'Cholesky' in the entire book…
Another source…
