This data set contains observations of abalones, the common name for any of a group of sea snails. The goal is to predict the age of an individual abalone given physical measurements such as sex, weight, and height.
A list with two items representing 211 observations from 9 variables
sex of abalone, 1 for female
indicates that the person is an infant
longest shell measurement in mm
perpendicular to length in mm
height in mm including meat in shell
weight of entire abalone
weight of meat
weight of viscera
weight of shell
rings. +1.5 gives the age in years
Only a stratified sample of 211 rows of the original data set are used here.
