Comparison of Weibull exponents for second- and third-order statistics. Notes: For each subject, the overall Weibull exponents (see Methods) obtained from experiments based on pairs of parameters drawn from a single order are combined (geometric mean) to determine an overall exponent for each order. The Weibull exponents for third-order statistics are slightly (∼11%) higher than for second-order statistics (p ≈ 0.05, one-tailed paired t test, N = 6).
