bears: Age and physical measurement data for wild bears
Description
Wild bears were anesthetized, 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.
