    Hypothesis test for changes in variance using a statistic based in P-values in a time series of normal independent observations. by Armendáriz Hernández, Samuel Uriel

    Published 2015
    “…The present work proposes a Hypothesis Test to detect a shift in the variance of a series of independent normal observations using a statistic based on the p-values of the F distribution. Since the probability distribution function of this statistic is intractable, critical values were we estimated numerically through extensive simulation. …”
