SpNaBaEps-class: Class SpNaBaEps

In edelcallejoc/rspecies: A Spatial Data Mining Framework for Species Distribution Modelling

Description

SpNaBaEps is used to store Epsilon's parameters of the Naive Bayes model.

Usage

SpNaBaEps(Ecx, ...)

Arguments

Ecx	numeric matrix. See slot section for more details.
...	argument pass to other methods.

Value

An object of class SpNaBaEps. See slot section for more details.

Slots

Ecx

matrix with S rows and M columns. Each element represents the epsilon parameter ε(c|x). See SpNaBaMatrix.

Examples

# Using SpNaBaMatrix constructor ----------------------

a <- matrix(rbinom(100, 100, runif(100, 0, 0.1)), nrow = 10, ncol = 10,
  dimnames = list(paste0("id:", 1:10), letters[1:10]))

x.mat <- SpNaBaMatrix(freqmatrix = a)

# Counts calculation ----------------------------------

x.counts <- counts(x.mat)

# Probability calculation -----------------------------

x.probs <- probs(x.counts)

# Estimating epsilon ----------------------------------

x.eps <- epsilon(x.counts, x.probs)
