envelope: Envelope algorithm

In fdaPOIFD: Partially Observed Integrated Functional Depth

Envelope algorithm

Description

Code for obtaining the envelope Ji of a curve specified by the index i. The implementation is based on Algorithm 1 in [1]. References:

Usage

envelope(data, i, max_iter = 10)

Arguments

data	Data matrix.
i	Index of curve.
max_iter	Maximum number of nearest curves considered in for loop. By default, max_iter = 5.
