StatisticSettings_MakeModel_mcrals_mdatools

Makes a Multivariate Curve Resolution (MCR) model using Alternating Least Squares (ALS) based on the R package mdatools.

Usage

StatisticSettings_MakeModel_mcrals_mdatools(
  ncomp = NULL,
  cont.solver = "mcrals.nnls",
  spec.solver = "mcrals.nnls",
  exclrows = NULL,
  exclcols = NULL,
  verbose = FALSE,
  max.niter = 100,
  tol = 10^-6,
  info = ""
)

Arguments

ncomp

Integer (length 1) with the number of components to be calculated.

cont.solver

Character (length 1) with the name of the to solve the pure components contributions (see details in mcrals).

spec.solver

Character (length 1) with the name of the function to solve the pure components spectra (see details in mcrals).

exclrows

Integer vector with the row indices to be excluded.

exclcols

Integer vector with the column indices to be excluded.

verbose

Logical (length 1) indicating if the function should be verbose.

max.niter

Integer (length 1) with the maximum number of iterations.

tol

Numeric (length 1) with the tolerance for convergence.

info

Character (length 1) with additional information.

Value

A StatisticSettings_MakeModel_mcrals_mdatools object.

Note

The functionality to define the initial pure components spectra as well as forcing concentration and spectra values are not included in this integration of mcrals.
