Simple linear regression analysis formula
WebbA linear regression equation takes the same form as the equation of a line, and it's often written in the following general form: y = A + Bx. Here, ‘x’ is the independent variable … WebbThe line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.
