funsMuVarPEend.int: Returns the mean and (asymptotic) variance of arc density of Proportional Edge Proximity Catch Digraph (PE-PCD) for 1D data - end interval case

Description

Two functions: muPEend.int and asyvarPEend.int.

muPEend.int returns the mean of the arc density of PE-PCD and asyvarPEend.int returns the asymptotic variance of the arc density of PE-PCD for a given expansion parameter \(r \ge 1\) for 1D uniform data in the left and right end intervals for the interval \((a,b)\).

See also (ceyhan:metrika-2012;textualpcds).

Usage

muPEend.int(r)
asyvarPEend.int(r)

Value

muPEend.int returns the mean and asyvarPEend.int returns the asymptotic variance of the arc density of PE-PCD for uniform data in end intervals

Arguments

r

A positive real number which serves as the expansion parameter in PE proximity region; must be \(\ge 1\).
