hellinger: Hellinger distance

Description

The function hellinger estimates the Hellinger distance between two random samples whose underdyling distributions are continuous.

Usage

hellinger(x, y, lower = -Inf, upper = Inf, method = 1, ...)

Arguments

x

numeric. A vector giving the first sample.

y

numeric. A vector giving the second sample.

lower

numeric. Lower limit passed to integrate.

upper

numeric. Upper limit passed to integrate.

method

integer. If method=1, the usual definition of the Hellinger distance is used; if method=2, an alternative formula is used.

...

Additional parameters to be passed to densityfun.

Value

A numeric value.

Details

Probability density functions are estimated with densityfun. Then numeric integration is performed with integrate.
