tupdate_modek: Update the mode k variational density.

In kkdey/flashr: Factor Loading Adaptive SHrinkage in R

Description

Update the mode k variational density.

Usage

tupdate_modek(Y, ex_list, ex2_vec, esig, k, mixcompdist = "normal",
  which_na = NULL, nullweight = 10)

Arguments

Y	An array of numerics. The data array.
ex_list	A list of vectors of numerics. The expected values of the components of each mode.
ex2_vec	A vector of positive numerics. The expected value of x'x for each mode.
esig	A positive numeric. The expected value of the precision.
k	A positive integer. The current mode to update.
mixcompdist	The mixing distribution to assume. Defaults to normal. Options are those available in the ashr package.
which_na	Either NULL (when complete data) or an array of logicals the same dimension as Y, indicating if the observation is missing (TRUE) or observed (FALSE).
nullweight	A numeric greater than or equal to 1. The penalty term on the probability of a component being zero.

Value

ex_list A list of vectors of the starting expected values of each component.

ex2_vec A vector of starting values of E[x'x]
