Abstract

Expressions have been derived for optimal interval widths in fixed-interval univariate histograms (Scott, 1979), fixed-interval bivariate histograms (Nezames, 1980), and variable-interval univariate histograms (Terrell and Scott, 1983). The present paper presents a computational method for the derivation of optimal fixed- and variable-interval bivariate cell dimensions as well as a construction method for several varieties of bivariate histograms.
