PLSDA: Partial least squares discriminant analysis

Description Usage Arguments Details Value References Examples

View source: R/PLSDA_class.R

Description

PLS is a multivariate regression technique that extracts latent variables maximising covariance between the input data and the response. The Discriminant Analysis variant uses group labels in the response variable and applies a threshold to the predicted values in order to predict group membership for new samples.

Usage

1
PLSDA(number_components = 2, factor_name, ...)

Arguments

number_components

(numeric, integer) The number of PLS components. The default is 2.

factor_name

(character) The name of a sample-meta column to use.

...

Additional slots and values passed to struct_class.
