Graphical displays which show inter--sample distances are important for the interpretation and presentation of multivariate data. Except when the displays are two--dimensional, however, they are often difficult to visualize as a whole. A device, based on multidimensional unfolding, is described...

This paper provides an introduction to the main types of graph in Stata that economics students might need. It covers univariate discrete and continuous variables, bivariate distributions, some simple time plots and methods of visualising the output from estimating models. It shows a small...

When the behaviour of a specific hypothesis test statistic is studied by a Monte Carlo experiment, the usual way to describe its quality is by giving the empirical level of the test. As an alternative to this procedure, we use the empirical distribution of the obtained \emph{p-}values and...
