density.estimate: Density estimate

In tomor14/Examst522:

Description

Estimate the density of a variable, either using the naive estimator og the Gaussian kernel estimator.

Usage

density.estimate(x, d, h, method)

Arguments

x	is a numeric variable.
d	is a point to obtain the density. d has to be a positive integer.
h	is bandwith. h has to be a positive numeric.
method	is either the naive estimator or the Gaussian kernel estimator. The default is the naive estimator.

Value

If d is given, it returns the density for the point d. If d is not given, it returns a list containing the density to the following points: min, 1st quartile, median, mean, 3rd qurtile and max.
