Description

Calculate out of sample total square error cost of using mean of points to estimate other points in interval. Zero indexed.

Usage

const_cost(y, w, min_seg, i, j)

Arguments

y	NumericVector, values to group in order.
w	NumericVector, weights.
min_seg	positive integer, minimum segment size (>=1).
i	integer, first index (inclusive).
j	integer, j>=i last index (inclusive);

Value

scalar, const cost of [i,...,j] interval (inclusive).

Examples

const_cost(c(1, 1, 2, 2), c(1, 1, 1, 1), 1, 0, 3)
