Abstract
Modern computing equipment is extremely fast and can also provide graphical out-put. 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.

Robust Tests for the Equality of Variances

TL;DR: In this paper, alternative formulations of Levene's test statistic for equality of variances are found to be robust under nonnormality, using more robust estimators of central location in place of the mean.

An Alternative Family of Transformations

TL;DR: In this article, an example of data for which the power family transformation does not produce satisfactory distributional properties is discussed, and an alternative one-parameter family of transformations is suggested.

Logarithmic transformations in ANOVA.

TL;DR: The method has advantages similar to those of rank transformations--namely, it is easy to use and is resistant to extreme observations, and is a useful generalization of least squares.

Applied Regression Analysis

TL;DR: In this article, the Straight Line Case is used to fit a straight line by least squares, and the Durbin-Watson Test is used for checking the straight line fit.

An Analysis of Transformations

TL;DR: In this article, Lindley et al. make the less restrictive assumption that such a normal, homoscedastic, linear model is appropriate after some suitable transformation has been applied to the y's.
