Age and physical measurement data for wild bears.
Description
Wild bears were anaesthetised, and their bodies were measured and weighed. One goal of the study was to make a table (or perhaps a set of tables) for people interested in estimating the weight of a bear based on other measurements. Notice that there are missing values for some of the variables.
