In plmmr: Penalized Linear Mixed Models for Correlated Data

Untransform coefficient values back to the original scale for file-backed data

Description

This function unwinds the initial standardization of the data to obtain coefficient values on their original scale. It is called by plmm_format().

Usage

untransform_plink(
  std_scale_beta,
  p,
  std_X_details,
  plink_flag,
  use_names = TRUE
)

Arguments

std_scale_beta	The estimated coefficients on the standardized scale
p	The number of columns in the original design matrix
std_X_details	A list with 3 elements describing the standardized design matrix BEFORE rotation; this should have elements 'scale', 'center', and 'ns'
use_names	Logical: should names be added? Defaults to TRUE. Set to FALSE inside of cvf() helper, as 'ns' will vary within CV folds.

Value

a matrix of estimated coeffcients, 'beta_vals', that is on the scale of the original data.
