The\nordinary least squares version 'kah3.test()' refers the ratio\nof the largest to the smallest residual mean square to its\nexact null distribution, Hartley's maximum F-ratio with three\ngroups; the robust version 'kah.robust.test()' replaces the\nmean squares by least trimmed squares scales, so that outliers\nneither create nor hide heteroscedasticity, and refers the\nratio to a maximum F-ratio with simulated effective degrees of\nfreedom, to a Monte Carlo reference or to a residual bootstrap.\nThe distribution, density, quantile and random generation\nfunctions of the maximum F-ratio are provided, together with\n'run.all.het()', which runs the proposed tests next to the\nGoldfeld-Quandt, Breusch-Pagan, White and robust modified\nGoldfeld-Quandt tests in one call.
