Data Science and Machine Learning with R - Linear Regression: A Simple Model Introduction

The video tutorial introduces linear regression as a foundational concept in machine learning, emphasizing its role in understanding data modeling. It explains the creation and purpose of models, the concept of fitted models, and their limitations. The tutorial also covers overfitting, underfitting, and the bias-variance tradeoff, providing insights into model generalization. Finally, it discusses methods to quantify the distance between data and models, focusing on accuracy and error minimization.
