pinvr: Moore-Penrose generalized inverse of a matrix

In aprodi/methyLImp: Missing Value Estimation of DNA Methylation Data

Description

Computes the Moore-Penrose generalized inverse of a matrix. Allows rank reduction of the generalized inverse.

This function is directly taken from MASS package (code on GPLv3 license) and modified in order to include the rank reduction option. The added code for rank reduction is commented in the implementation.

Usage

pinvr(X, max.sv = min(dim(X)), tol = sqrt(.Machine$double.eps))

Arguments

X	Real or complex valued matrix to be transformed
max.sv	Maximum for single value decomposition
tol	Tolerance

Value

Returns the inverse logit transformed values.
