Linear Regression Calculator


The Linear Regression Calculator to calculate the relationship between two variables, the method is by fitting a linear equation to observed data.

Linear Regression Formula

The linear regression line is Y = A + BX, where Y is the dependent variable, X is the explanatory variable, The slope is B, and A is the intercept.

For example, Two stes {5,20,40,80,100}, {5,10,20,80,100}, Then Slope(B) is 1.0732, X Mean is 49, Y Mean is 43, Intercept(A) is -9.5872, So the Regression Equation Y= -9.5872 + 1.0732 x. provides you helpful and handy calculator resources.
