qdarob: Robust Quadratic Discriminant Analysis

In abnormally-distributed/cvreg: Cross Validation and Robust Estimation Utilities

Description

This model utilizes robust estimation in order to improve the performance of the standard quadratic discriminant. This is a heavy modification of MASS's qda function. Due to the substantial modifications the returned object is of its own "qdarob" class and has an accompanying predict method.

Usage

qdarob(
  formula,
  data,
  grouping,
  prior = proportions,
  method = c("rocke", "shr")
)

Arguments

formula	a model formula
data	a data frame
prior	a vector of prior probabilities for each class
method	the scale estimation method. one of "rocke" (cov.rocke) or "shr" (cov.shr)#' @return A qdarob object

Examples

qdarob(Species ~.,iris)
