Nonparametric statistics and model selection
... Suppose we want to see if a particular complex statistic is significantly different between two groups. If we don’t know the distribution of the statistic, then we can’t assign any particular probabilities to particular values, and so we can’t say anything interesting after computing a statistic fro ...

Would it be preferable to ask instead whether there is enough evidence to establish that the site is unacceptable? Explain. What assumptions about the number of pedestrians passing the location in an hour are nec ...
