Abstract

We investigate the use of power transformations when data on two quantitative variables are presented in a two-way table. Given a suitable transformation we can model theunderlying continuous variables. Regressions and the correlation are obtained from the transformed grouped data. Also, by transforming back to the original scale, we obtain a smoothed version of the data.
