RShapeTarget-package: Shape Target Distributions

In pierrejacob/RShapeTarget: Target Distributions based on shapes

Description

This package allows to create 2-dimensional probability distributions from SVG shapes.

Details

It's kinda fun and it allows to create multimodal target densities easily.

The idea is that a shape is essentially a set and we can define a probability density function proportional to

• 1 when x is inside the shape

• 0 when x is outside the shape

This density function is very discontinuous, so we can smooth it using a Gaussian kernel to define

f_lambda(x) = sup_theta f(theta) exp(-1/2lambda* distance(x,theta))

The parameter lambda controls the smoothness
