Description: Implements numerous methods for detecting heteroskedasticity 
    (sometimes called heteroscedasticity) in the classical linear regression 
    model. These include a test based on Anscombe (1961) 
    <https://projecteuclid.org/ euclid.bsmsp/1200512155>, Ramsey's (1969) 
    BAMSET Test <doi:10.1111/j.2517-6161.1969.tb00796.x>, the tests of Bickel 
    (1978) <doi:10.1214/aos/1176344124>, Breusch and Pagan (1979)  
    <doi:10.2307/1911963> with and without the modification

    Holt (2003) <doi:10.1080/0266476022000018475>, Cook and Weisberg (1983) 
    <doi:10.1093/biomet/70.1.1> (including their graphical methods), Diblasi 
    and Bowman (1997) <doi:10.1016/S0167-7152(96)00115-0>, Dufour, Khalaf,

    <doi:10.1080/10629360500107923>, and Zhou, Song, and Thompson (2015) 
    <doi:10.1002/cjs.11252>. Besides these heteroskedasticity tests, there are 
    supporting functions that compute the BLUS residuals of Theil (1965) 
    <doi:10.1080/01621459.1965.10480851>, the conditional two-sided p-values of 
    Kulinskaya (2008) <arXiv:0810.2124v1>, and probabilities for the 
    nonparametric trend statistic of Lehmann (1975, ISBN: 0-816-24996-1). 
    Homoskedasticity refers to the assumption of constant variance that is 
    imposed on the model errors (disturbances); heteroskedasticity is the 
    violation of this assumption.
