rubin2wt.all: 2nd Rubin's rule Within-Variance Component (all peptides)

In mi4p: Multiple Imputation for Proteomics

2nd Rubin's rule Within-Variance Component (all peptides)

Description

Computes the within-variance component in the 2nd Rubin's rule for all peptides.

Usage

rubin2wt.all(
  data,
  funcvar = mi4p::within_variance_comp_emmeans,
  metacond,
  is.parallel = FALSE,
  verbose = TRUE
)

Arguments

data	dataset
funcvar	function that should be used to compute the variance
metacond	a factor to specify the groups
is.parallel	should parallel computing be used?
verbose	should messages be displayed?

Value

List of variance-covariance matrices.
