CriticalValues: Critical Values of Tests of Change-Point(s) with One-Change...

In sac: Semiparametric Analysis of Change-Point

Description

Return the approximate critical values of the test statistics given level alfa

Usage

Sn.alfa(alfa,n,d,model=c("parametric","semiparametric"),
        tol = .Machine$double.eps^0.25, maxiter = 1000)
CV.Epidemic.Vn(alfa, d, tol = 1e-10)
CV.Epidemic.Wn(alfa, tol = 1e-07)

Arguments

alfa	significance level
n	sample size
model	a character string specifying the model, must be one of "parametric" or "semiparametric" (default). You can specify just the initial letter
d	dimension of the data value
tol	the desired accuracy (convergence).
maxiter	the maximum number of iterations for uniroot.

Details

Function Sn.alfa returns the critical value of Sn for one-change alternative. The functions CV.Epidemic.Vn and CV.Epidemic.Wn calculate critical values for Vn and Wn.
