Description

This function plots the contribution value for each variable of a newly monitored observation and compares them to the contribution values of the training data.

Usage

2
mspContributionPlot(trainData, trainLabel, newData, newLabel, var.amnt,
  trainObs)

Arguments

trainData

an xts data matrix containing the training observations

trainLabel

Class labels for the training data as a logical (two states only) or finite numeric (two or more states) vector or matrix column (not from a data frame) with length equal to the number of rows in “data." For data with only one state, this will be a vector of 1s.

newData

an xts data matrix containing the new observation

newLabel

the class label for the new observation

var.amnt

the energy proportion to preserve in the projection, which dictates the number of principal components to keep

trainObs

the number of observations upon which to train the algorithm. This will be split based on class information by a priori class membership proportions.

Value

A contribution plot and a list with the following items:
