Updated: Nov 3, 2021

Description :

This dataset explains the cost of a small sample of USA population Medical Insurance Cost based on some attributes such as age, sex, bmi etc.

This dataset corresponds to a practical used in the book Machine Learning with R by Brett Lantz; which is a book that provides an introduction to machine learning using R. All of these datasets are in the public domain but simply needed some cleaning up and recoding to match the format in the book.

Recommended Model :

Algorithms to be used: Regression, SVM, RandomForestRegressor etc.

Recommended Project :
