As the linear regression has a closed form solution, the regression coefficients can be efficiently computed using the Regress method of this class. Enter two data sets and this calculator will find the equation of the regression line and correlation coefficient. References: In linear regression, the model specification is that the dependent variable, y is a linear combination of the parameters (but need not be linear in the independent variables). This linear regression calculator uses X and Y values to determine the regression equation. As the linear regression has a closed form solution, the regression coefficients can be efficiently computed using the Regress method of this class. Use the line regression calculator to find the regression equation. In linear regression, the model specification is that the dependent variable, y is a linear combination of the parameters (but need not be linear in the independent variables). The best fit line always passes through the point ( x ¯, y ¯). The sample means of the x values and the x values are x ¯ and y ¯, respectively. Linear regression analysis is the most widely used of all statistical techniques. It turns out that the line of best fit has the equation: (12.4.2) y a + b x. The slope of the line is b, and a is the intercept (the value of y when x = 0). Simple linear regression is useful for finding relationship between two continuous variables.Ī linear regression line has an equation of the form Y = a + bX, where X is the independent variable and Y is the dependent variable. This Slope and y-intercept Calculator calculates the best-fitting slope and best-fitting y-intercept for a linear line based on the given data points.

Linear regression is used for finding linear relationship between target and one or more predictors. In statistics, linear regression is a linear approach to modeling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables).
