Polynomial stitched (PS) boundary

Source: R/utils.R
ps_boundary.Rd

Alternative boundary for both Theorem 1 and Theorem 2 constructions, included for completeness and for cross-checking CR23 Table results.

Usage

ps_boundary(v, alpha, v_opt = 10, c = 1, s = 1.4, eta = 2)

Arguments

v

Numeric vector >= 0. Intrinsic time values.

alpha

Numeric in (0,1). ONE-SIDED significance level.

v_opt

Numeric > 0. Optimal intrinsic time (= m in H21). Default: 10.

c

Numeric > 0. Sub-exponential scale.

s

Numeric > 1. Stitching parameter. Default: 1.4.

eta

Numeric > 1. Geometric spacing. Default: 2.

Value

Numeric vector of boundary values (cumulative-sum scale).

Details

This is not the recommended primary boundary: the CM/GE mixture boundaries (cm_boundary(), ge_boundary()) are tighter in CR23 and are used by default throughout seqcomp. Use ps_boundary() only when you specifically need the polynomial-stitched construction.

Examples

ps_boundary(v = 1:5, alpha = 0.025, v_opt = 10, c = 1)
