A Comparative Study of Tests for Homogeneity of Variances, with Applications to the Outer Continental Shelf Bidding Data

摘要: Many of the existing parametric and nonparametric tests for homogeneity variances, some variations these tests, are examined in this paper. Comparisons made under null hypothesis (for robustness) alternative power). Monte Carlo simulations various symmetric asymmetric distributions, sample sizes, reveal a few that robust have good power. These further compared using data from outer continental shelf bidding on oil gas leases.
