ks2d

Contents

Definition:

ks2d returns the 2D kernel density at point (x, y) with specified bandwidth method and density method. Refer to this page for detailed algorithm.

Syntax:

 vector  ks2d(vector vx, vector vy[, int bandwidth, int grid, int interp, int density])

Parameters:

vx

is a vector of X coordinate values which you want to calculate the kernel density.

xy

is a vector of Y coordinate values which you want to calculate the kernel density.

bandwidth

is the bandwidth method of the 2D Kernel Density. Optional.

grid

is the number of equally spaced grid points for the density estimation. Only meaningful for bandwidth=0. Default is 151.

interp

determines whether to interpolate density points: 0=false, 1=true(default). Optional..

density

is the density method. Only meaningful for interp=1.

Return:

Returns the 2D kernel density with specified bandwidth method and density method.
