Co.UPM: Co‑Upper Partial Moment

Description

Computes the co‑upper partial moment (upper‑right quadrant 1) between two equal‑length numeric vectors at any degree and target.

Usage

Co.UPM(degree_upm, x, y, target_x, target_y)

Value

Numeric vector of co‑UPM values.

Arguments

degree_upm

numeric; degree = 0 gives frequency, degree = 1 gives area.

x

numeric vector of observations.

y

numeric vector of the same length as x.

target_x

numeric vector; thresholds for x (defaults to mean(x)).

target_y

numeric vector; thresholds for y (defaults to mean(y)).
