Linear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit. This calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used.
Use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient. It also produces the scatter plot with the line of best fit.
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 linear regression calculator generates the linear regression equation. It also draws: a linear regression line, a histogram, a residuals QQ-plot, a residuals x-plot, and a distribution chart.

Jan 18, 2024 · Use this least squares regression line calculator to fit a straight line to your data points using the least square method.
There are two things we need to get the estimated regression equation: the slope (b 1) and the intercept (b 0). The formulas for the slope and intercept are derived from the least squares method: min Σ(y - ŷ) 2. The graph of the estimated regression equation is known as the estimated regression line.
