SVT: SVT

In jdrhyne2/FastLORS: Joint Modeling for eQTL Mapping in R

Description

SVT is a function to perform soft-thresholded singular value decomposition. It is used to get an initial estimate for L. Note: This function is adapted from the LORS MATLAB implementation

Usage

SVT(Y, lambda)

Arguments

Y	gene expression matrix
lambda	a tuning parameter

Value

L the singular value decomposition of Y, soft-thresholded with lambda.

Examples

##Example
set.seed(123)

Y <-matrix(rnorm(50*100, 7,1), nrow = 50, ncol = 100)
lambda <- runif(1,3,5)
SVT(Y, lambda)
