Linear regression A lgorithm Concept of Linear regression In order to model the relationship between a dependent variable and one or more independent variables, linear regression is a machine learning algorithm. The goal of linear regression is to find a linear equation that best describes the relationship between the variables. Using the values of the independent variables as a starting point, this equation can then be used to predict the value of the dependent variable. There is simply one independent variable and one dependent variable in basic linear regression. The linear equation takes the form of y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept. For example, let's say we have a dataset of the number of hours studied and the corresponding test scores of a group of students. We can use linear regression to find the relationship between the two variables and predict a student's test scor
