compute_mahalanobis_distance.simple: Squared Mahalanobis Distance
Description
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.
Usage
compute_mahalanobis_distance.simple(phylo, Y_data_vec, sim, Sigma_YY_chol_inv, miss = rep(FALSE, dim(sim)[1] * length(phylo$tip.label)), ...)
Arguments
sim
(list) : result of function simulate.
Y_data
: vector indicating the data at the tips.
Sigma_YY_inv
: invert of the variance-covariance matrix of the data.
Value
squared Mahalanobis distance between data and mean at the tips.
Details
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.
