plotDiscrimClass: Barplot of the discriminative power of the classes

In RMixtCompUtilities: Utility Functions for 'MixtComp' Outputs

Barplot of the discriminative power of the classes

Description

Barplot of the discriminative power of the classes

Usage

plotDiscrimClass(output, ylim = c(0, 1), pkg = c("ggplot2", "plotly"), ...)

Arguments

output	object returned by mixtCompLearn function from RMixtComp or rmcMultiRun function from RMixtCompIO
ylim	vector of length 2 defining the range of y-axis
pkg	"ggplot2" or "plotly". Package used to plot
...	arguments to be passed to plot_ly

Details

The discriminative power of class k is defined by 1 - D(k)

D(k) = -\sum_{i=1}^n P(Z_i=k|x_i) \log(P(Z_i=k|x_i)) / (n*\exp(-1))
