ginv: G inverse
In MultBiplotR: Multivariate Analysis Using Biplots in R
ginv R Documentation
G inverse
Description
Calculates the g-inverse of a squared matrix using the eigen decomposition and removing the eigenvalues smaller than a tolerance.
Usage
ginv(X, tol = sqrt(.Machine$double.eps))
Arguments
X
Matrix to calculate the g-inverse
tol
Tolerance.
Details
The function is useful to avoid singularities.
Value
Returns the g-inverse
Author(s)
Jose Luis Vicente Villardon
Examples
data(iris)
x=as.matrix(iris[,1:4])
S= t(x)
ginv(S)
