To solve this issue I propose the following:
-
On point 1, instead of modelling and sampling the whole covariance matrix, do it with just the lower/upper half over the diagonal, and when creating the model from sampled parameters, completing the other half using simetry over diagonal, that is:
matrix[i][j] = matrix[j][i]
-
For the second point, I will transform the standard deviation using the positive transformer mentioned here before modelling and reverse transform it when recreating the model.
