Linear Regression Calculator. This simple linear regression calculator uses the least squares method to find the line of best fit for a set of paired data, allowing you to estimate the value of a dependent variable ( Y) from a given independent variable ( X ). The line of best fit is described by the equation ŷ = bX + a, where b is the slope ...
What is the formula for linear regression?The simple linear regression model is y = β 0 + β1 x + ∈. If x and y are linearly related, we must have β 1 # 0. The purpose of the t test is to see whether we can conclude that β 1 # 0. We will use the sample data to test the following hypotheses about the parameter β 1.
How to perform simple linear regression?Simple linear regression is a technique that we can use to understand the relationship between one predictor variable and a response variable.. This technique finds a line that best “fits” the data and takes on the following form: ŷ = b 0 + b 1 x. where: ŷ: The estimated response value; b 0: The intercept of the regression line; b 1: The slope of the regression line
