To me it seems like returning chi-sq = 0 and p-value = 1 would make sense. It would also be consistent with other scenarios of equal variance in all groups. One example:
fligner.test(1:8, gl(2,4)) # Fligner-Killeen test of homogeneity of variances # # data: 1:8 and gl(2, 4) # Fligner-Killeen:med chi-squared = 0, df = 1, p-value = 1 But I am aware that other tests implemented in stats:: sometimes throw errors in similar situations. Maybe someone more familiar with the behaviour and philosophy behind stats:: preferences can add more weight here? Warm regards, Karolis K.
