untransform {plmmr} | R Documentation |
Untransform coefficient values back to the original scale
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(
std_scale_beta,
p,
std_X_details,
fbm_flag,
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' |
fbm_flag |
Logical: is the corresponding design matrix filebacked? |
plink_flag |
Logical: did these data come from PLINK files?
Note: This flag matters because of how non-genomic features
are handled for PLINK files – in data from PLINK files,
unpenalized columns are not counted in the |
use_names |
Logical: should names be added? Defaults to TRUE. Set to FALSE inside of |
Value
a matrix of estimated coeffcients, 'beta_vals', that is on the scale of the original data.
