Nettet28. okt. 2024 · In this guide, we will learn how to build a Simple Linear Regression Model using Sci-kit Learn. Simple Linear Regression is a regression algorithm that shows the relationship between a single independent variable and a dependent variable. The Sci-kit Learn library contains a lot of tools used for machine learning. Numerous extensions of linear regression have been developed, which allow some or all of the assumptions underlying the basic model to be relaxed. The very simplest case of a single scalar predictor variable x and a single scalar response variable y is known as simple linear regression. The extension to multiple and/or vector-valued predictor variables (denoted with a capital X) is k…
