I've made fligner test with the same data, changing the orders of the
variables, and this what i get
> fligner.test(rojos~edadysexo*zona*ano*estacion)
Fligner-Killeen test of homogeneity of variances
data: rojos by edadysexo by zona by ano by estacion
Fligner-Killeen:med chi-squared = 15.7651, df = 2, p-value = 0.0003773
> fligner.test(rojos~ano*edadysexo*zona*estacion)
Fligner-Killeen test of homogeneity of variances
data: rojos by ano by edadysexo by zona by estacion
Fligner-Killeen:med chi-squared = 86.5317, df = 3, p-value < 2.2e-16
Different results with the same variables!!! Why? i try to find an answer,
but i really surprised
