Re: Intrapermutations to test two different mean values

Followup
It was seen that the Hsu solution gave [1.720, 2.700] as the (central) 95% Confidence Interval (5% significance level ). It is interesting to check how noparametric techniques behave before this spider?s problem. In this intention we performed: __1) Bootstrap samples falling inside Hsu solution (2 experiments, 1 million each one): 0.97143, 0.97155. __2) Intrapermutation: 0.97483, 0.97484.
Conclusion In comparison with the Hsu test the noparametric leads to lower the probability to reach significant values at this 5% level. To be close to this level Intrapermutations provides a slightly worse result than Bootstrap.
