Finding linear regression
WebSep 3, 2024 · The linear regression tries to find out the best linear relationship between the input and output. y = θx + b # Linear Equation. The goal of the linear regression is to find the best values for θ and b that represents the given data. We will learn more about it in a detailed manner later in this article. WebMathematically, the linear relationship between these two variables is explained as follows: Y= a + bx Where, Y = dependent variable a = regression intercept term b = regression slope coefficient x = independent variable “a” and “b” are also called regression coefficients. And Excel returns the predicted values of these regression coefficients too.
