The normal distribution is the probability distribution that plots all of its values along a symmetrical bell curve, with the highest probabilities centered around the mean value and tapering out ...

It is demonstrated that probabilities for the distribution of the sample correlation coefficient, such as those given by David [2] can be quickly and accurately calculated on modern desk calculators.

We give a large-sample analysis of the minimal coverage probability of the usual confidence intervals for regression parameters when the underlying model is chosen by a "conservative" (or ...
