Introduction
In the previous chapter, we understood linear regression models and the linear relationship between an input variable (independent variable) and a target variable (dependent variable or explanatory variable). If one variable is used as an independent variable, it is defined as simple linear regression. If more than one explanatory (independent) variable is used, it's called multiple linear regression.
Regression algorithms and problems are based on predicting a numeric target variable (often called dependent), given all the input variables (often called independent variables), for example, predicting a house price based on location, area, proximity to a shopping mall, and many other factors. Many of the concepts of regression are derived from statistics.
The entire field of machine learning is now a right balance of mathematics, statistics, and computer science. In this chapter, we will use regression techniques to understand how to establish a relationship between input(s) and...
