You need to work with dataset bears.xlsx. The goal of this project is letting students explore the dataset, analyze the dataset. build regression models, and interpret the modeling results. Regression Case Study A study is conducted on the greatest threat to humanity, bears. Field studies collect data on the following characteristics of bears in the wild: Variable Description Age age of bear Sex sex of bear Head Length distance from tip of nose to back of head Head Width distance from outer edge of left ear to outer edge of right ear Neck Girth circumference of the neck Length distance from foot to top of head Chest Girth circumference of the chest Weight weight of bear The data are collected by tranquilizing the bear and taking the measurements. Weighing an unconscious bear in the field proves to be very difficult. Our task is to predict bear weight based on the other measurements.
