Regression Equation Calculator. Home mathematics regression. Enter all known values of x and y into the form below and click the calculate button to calculate the linear regression equation.
The calculator will generate a step by step explanation along with the graphic representation of the data sets and regression line. A linear regression line has an equation of the form y a bx where x is the explanatory variable and y is the dependent variable. B the slope of the regression line a the intercept point of the regression line and the y axis.
The slope of the line is b and a is the intercept the value of y when x 0.
Linear regression calculator. Correlation and regression calculator enter two data sets and this calculator will find the equation of the regression line and corelation coefficient. Number of inputs for x and number of inputs for y must be same. N number of values or elements x first score y second score σxy sum of the product of first and second scores σx sum of first scores σy sum of second scores σx2 sum of square first scores.
