compute_mahalanobis_distance.simple
computes the squared Mahalanobis distance
between the data and mean at tips of the data in the simple case where the inverse
of the variance matrix is given.

phylo |
Input tree. |
Y_data_vec |
: vector indicating the data at the tips. |
sim |
(list) : result of function |
Sigma_YY_chol_inv |
: invert of the cholesky variance-covariance matrix of the data. |
This function takes parameters sim and Sigma_YY_inv from
compute_mean_variance.simple
. It uses function extract_simulate_internal
to extract the needed quantities from these objects.
