Table 8.

Proportion of error type I (for a = 0.05), for some representative of the 768 simulation scenarios that did not have signal, using the different permutation methods, and with G as the statistic in the absence of EB (so, equivalent to the F statistic). Confidence intervals (95%) are shown in parenthesis.

N: number of observations; x1 and z1: regressors of interest and of no interest, respectively, being either continuous (c) or discrete (d). ρ: correlation between x1 and z1; Inline graphic: model partitioned or not (using the scheme of Beckmann et al. (2001), shown in Appendix A"); ϵ: distribution of the simulated errors, which can be normal (N), uniform (U), exponential (E) or Weibull (W); ee: errors treated as exchangeable; ise: errors treated as independent and symmetric. The methods are the same shown in Table 2: Draper–Stoneman (D–S), Still–White (S–W), Freedman–Lane (F–L), ter Braak (tB), Kennedy (K), Manly (M), Huh–Jhun (H–J), Smith (S) and parametric (P), the last not using permutations.
