Description

The FRaC Algorithm

Usage

1
frac(x,  models, n.cv=2, keys = NULL grid=NULL, allowParallel = FALSE, tuneList = NULL)

Arguments

x

An NxT matrix with T observations of N varialbles

models

a string vector of models available in the caret package

keys

A vector of integers representing places that the data set has time variables. This is only here for short term bug fixes

n.cv

An integer specifying the number of cross-validations

allowParallel

Logical definining whether or not the user would like to use a parallel backend if one is set up

tuneList

A list of models for train functions

grid

A list containing the different parameter values for each models iterations. Can be set to default NULL

Details

Version 0.0.3 Alpha

Value

values or sup: the normalised suprisal score for each observation. Higher scores equate to a higher chance of an observation being an outlier
