How to solve simple linear regression
WebApr 8, 2024 · The Formula of Linear Regression. Let’s know what a linear regression equation is. The formula for linear regression equation is given by: y = a + bx. a and b can be computed by the following formulas: b= n ∑ xy − ( ∑ x)( ∑ y) n ∑ x2 − ( ∑ x)2. a= ∑ y − b( ∑ x) n. Where. x and y are the variables for which we will make the ... WebTo find the best fitting line, we need to minimize the sum of the squared differences between the observed values of the dependent variable and the values predicted by the regression line. This is called the least squares method. There are two types of linear regression: simple linear regression and multiple linear regression.
