compute_ordinal_auxiliary_trait_elbo: Ordinal Trait ELBO

In jpmeagher/vbar: Variational Bayes Ancestral Reconstruction

Ordinal Trait ELBO

Description

Compute the contribution of an ordinal trait to the Evidence Lower Bound (ELBO) of a PLVM given the approximate posterior distribution for loadings and latent traits.

Usage

compute_ordinal_auxiliary_trait_elbo(
  y,
  cut_off_points,
  loading_expectation,
  latent_trait_expectation,
  loading_outer_expectation,
  latent_trait_outer_expectation,
  perform_checks = TRUE
)

Arguments

y	An N-dimensional vector of ordered factors with K levels. An ordinal manifest trait.
cut_off_points	A K+1 dimensional ordered vector of values. The cut off points separating auxiliary traits into ordinal state.
loading_expectation	A L-dimensional vector of real numbers, The row of the expected loading matrix corresponding to the ordinal trait.
latent_trait_expectation	An NxL matrix of real values. The expected individual specific latent traits.
loading_outer_expectation	A LxL matrix. The expected outer product for the row of the expected loading matrix corresponding to the ordinal trait.
latent_trait_outer_expectation	A LxLxN array, The expected outer product of individual specific latent traits.
perform_checks	Logical. Check if function inputs are specified correctly.

Value

A real valued scalar. The contribution of the ordinal trait to the ELBO.
