spflp1 {mbreaks}

SupF(l+1|l) test

Description

Function computes the test statistics of supF(l+1|l) test with null hypothesis is l=nseg-1 and alternative hypothesis is l+1. The l breaks under the null hypothesis are taken from the global minimization.

spflp1 computes the test statistics of supF(l+1|l) test with null hypothesis is l=nseg-1 and alternative hypothesis is l+1. The l breaks under the null hypothesis are taken from the global minimization.
