checkerboardDensity {RDM}

Estimate the checkerboard mass density

Description

Estimate a non-square checkerboard mass density

Usage

checkerboardDensity(X, Y, resolution1, resolution2)

Arguments

X

First coordinate of the observations.

Y

Second coordinate of the observations.

resolution1

A natural number specifying the resolution of the first component.

resolution2

A natural number specifying the resolution of the second component.

Details

This implementation modifies the code of build_checkerboard_weights() published in 'qad', version 1.0.4, available at https://CRAN.R-project.org/package=qad, to allow for non-square checkerboard mass densities. For more details on the implementation see ECBC and for more information on the implemented changes, see the file 'src/code.cpp'.

Value

The estimated checkerboard mass density.

Examples

checkerboardDensity(runif(20), runif(20), 3, 3)
