This function generates a standardized univariate upper partial moment
of any non‑negative degree for a given target.
Usage
UPM.ratio(degree, target, variable)
Arguments
- degree
numeric; degree = 0 gives frequency, degree = 1 gives area.
- target
numeric vector; threshold(s). Defaults to mean(variable).
- variable
numeric vector or data‑frame column to evaluate.
Value
Numeric vector of standardized upper partial moments.
