In jpmeagher/vbar: Variational Bayes Ancestral Reconstruction

Taxon Specific Latent Trait Trait ELBO

Description

Compute the contribution of taxon specific latent traits to the Evidence Lower Bound (ELBO) of a PLVM given the approximate posterior distribution for loadings and latent traits

Usage

compute_taxon_specific_latent_trait_elbo(
  taxon_specific_latent_trait_expectation,
  taxon_specific_latent_trait_outer_product_expectation,
  taxon_specific_latent_trait_covariance,
  phy,
  phylogenetic_gp,
  perform_checks = TRUE
)

Arguments

taxon_specific_latent_trait_expectation	A (2S - 1)xL matrix of real values. The expected value of the taxon specific latent traits.
taxon_specific_latent_trait_outer_product_expectation	A LxLx(2S - 1) array of real values. The expected outer product of taxon specific latent traits under the approximate posterior.
taxon_specific_latent_trait_covariance	A LxLx(2S - 1) array of real values. The covariance of taxon specific latent traits under the approximate posterior.
phy	An object of class "phylo".
phylogenetic_gp	A (2S - 1)x2xL array of real values. Hyperparameters for the Gaussian process over phy.
perform_checks	Logical. Check if function inputs are specified correctly.

Value

A real valued scalar. The contribution of taxon specific latent traits to the ELBO.
