chi2_ECden {TOHM}

Compute Euler characteristic density for Chi-square random fields

Description

Computes the Euler characteristic (EC) density of a given order for Chi-squared random fields.

Usage

chi2_ECden(c, k, j)

Arguments

c

Value on which the EC density is evaluated.

k

Degrees of freedom of the Chi-square random field.

j

Order of the EC density to be implemented.

Value

Returns the value of the EC density of order j evaluated at c for a Chi-square random field with k degrees of freedom.
