epsilon: Correlation method for the Spatial Naive Bayes Model

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

Description

epsilon is a function to estimates epsilon parameter for the Spatial Naive Bayes Model.

Usage

## S4 method for signature 'SpNaBaCounts,SpNaBaProbs'
epsilon(x.counts, x.probs)

Arguments

x.counts	A SpNaBaCounts object.
x.probs	A SpNaBaProbs object.

Value

epsilon: An object of class SpNaBaEps.

Examples

# Using the function id_pts() for spatial data --------

library(sp)
library(rgeos)
library(rgdal)
library(raster)

# Loading data
data(Mex0)
data(mammals)

# Generating de grid from Mex0 data
Mex0.grd<-grd_build(Mex0)

# Identification points of mammals
x.mat<-id_pts(grd = Mex0.grd, pts = mammals)

# Without target declaration --------------------------

system.time(x.counts <- counts(x.mat))

# With target declaration -----------------------------

x.counts <- counts(x.mat, target = 1:10)

# Probability matrices -----------------------------------
x.probs <- probs(x.counts, fac.lap = 0.1)

# Epsilon parameter -----------------------------------

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