get_line1_2_15_doubletree: calculate line 1, 2, and 15 of ELBO*

In zhenkewu/doubletree: Nested Latent Class Models for Domain-Adaptive and Semisupervised Learning of Cause-of-Deaths using Verbal Autopsy

calculate line 1, 2, and 15 of ELBO*

Description

Intended to be faster than its counterpart implementation in R.

Usage

get_line1_2_15_doubletree(
  F,
  digamma_emat,
  rmat,
  emat,
  v1_lookup_NA_replaced,
  v2_lookup
)

Arguments

F	intermediate values from updates of rmat and emat; dimension: N by pL1 by K; currently for observations with known leaf labels in tree1 AND tree2, there is redundancy because once we know i, we know the leaf 1 label, hence no need for the second dimension
digamma_emat	matrix(pL1 by pL2)
rmat	matrix (N by K); row sums are one - the class probabilities for each observation.
emat	matrix (N by pL1)
v1_lookup_NA_replaced	vector; includes values of pL+1 for unknown leaf label in tree1.
v2_lookup	v2_lookup is a vector of length equal to the total number of rows in X; each element is an integer, indicating which leaf does the observation belong to in tree2

Details

This function updates the N by pL1 matrix emat in the package

Value

line 1, 2, 15 of the ELBO* in Appendix
