TRANSFORMATIONS: SOME EXAMPLES REVISITED.

Modern computing equipment is extremely fast and can also provide graphical output. Prior to the computer era, problems were often formulated in terms of a single numerical criterion which could be handled conveniently on a desk calculator. Now several aspects of a problem or several criteria can be considered simultaneously and a more flexible attitude adopted. The situation then can often be easily understood by the experimenter, and compromise decisions can be made by him. In this paper we consider the particular problem of transforming data from this viewpoint by re-examining some specific published examples.
