Truncated.NIPALSPCA

Truncated version of the NIPALS algorithm for PCA.

Truncated version of the NIPALS algorithm for PCA.

Truncated.NIPALSPCA(X, dimens = 2, tol = 1e-06, maxiter = 1000, lambda = 0.02)

`X`	The data matrix.
`dimens`	The dimension of the solution
`tol`	Tolerance of the algorithm.
`maxiter`	Maximum number of iteratios.
`lambda`	Value used for truncation

Classical NIPALS algorithm for the singular value decomposition that allows for the construction of PCA and Biplot.

The singular value decomposition

`u`	The coordinates of the rows (standardized)
`d`	The singuklar values
`v`	The coordinates of the columns (standardized)
