the use of spacings in goodness-of-fit testing

One of the important steps before performing any parametric statisticalanalysis is to conduct a formal goodness-of-fit (gof) testing. in this talk, we introducesomehow less known gof testing procedure based on spacings which has beenshown to have larger power in some cases in compare to the conventional empiricaldistribution function (edf)-based gof methods. indeed, gof testing based onspacings cover a large class of tests including the greenwood’s statistic, the moran’sstatistic and the quesenberry and miller’s statistic. gof tests based on higher orderspacings and some suggestions for new testing methodologies for the case of censoreddata will also be discussed.
