Nettet#Coded by Andrew Cimport pandas as pdimport numpy as npfrom sklearn import datasetsfrom sklearn.linear_model import LinearRegressionfrom sklearn.model_select... NettetThe term “linearity” in algebra refers to a linear relationship between two or more variables. If we draw this relationship in a two-dimensional space (between two variables), we get a straight line. Linear regression performs the task to predict a dependent variable value (y) based on a given independent variable (x).
