... Carrying out a hypothesis test amounts to deciding whether the value obtained for the test statistic could plausibly have resulted when H0 is true. When the value of the test statistic leads to rejection of H0, it is customary to say that the result is statistically significant a the chosen signific ...

conservative estimation of cdf - UFL MAE
... The neutral estimator of the standard deviation is, as we have seen analytically, biased; so the mean of the probability of failure estimator is less than the actual. Moreover, there is a five per cent chance to underestimate Pf by a factor of two (the lower bound of the confidence interval is 1.01% ...

Statistical Methods for Eliciting Probability
... questions about uncertain quantities are preferable to others, and appear to be more reliable. However data are lacking on exactly how well the various methods work, because it is unclear, other than by asking using an elicitation method, just what the person believes. Consequently one is reduced to ...

Moreover, no specific features of the fuzzy set theory are used except the notion of the membership functions, and thus this model could be rega ...
