Modern measurement techniques allow researchers to gather ever more data in less time. In many cases, however, the primary or raw data have to be further analyzed, be it for the verification of a ...

Goodness-of-fit statistics for general multiple-linear-regression equations are reviewed for the case of replicated responses. A modification of the coefficient of determination is recommended. This ...

We introduce a goodness-of-fit process for quantile regression analogous to the conventional R 2 statistic of least squares regression. Several related inference processes designed to test composite ...
