Abstract :
We apply a recently developed computational approach test to the one-way
fixed effects ANOVA models of log-normal data with unequal variances. The merits of
the proposed test are numerically compared with the existing tests - the James second
order test, the Welch test and the Alexander-Govern test - with respect to their sizes
and powers in different combinations of parameters and various sample sizes. The simulation
results demonstrate that the proposed method is satisfactory: its type I error
probability is very close to the nominal level. We illustrate these approaches using a
real example.
