Regression Line Calculator. The 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.
The 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. Y a bx input by clicking each cell in the table below. Linear regression calculator.
If data points are perfectly linear the sample correlation will either be 1 for a line with a positive slope or 1 for a line with a negative slope.
If you press and hold on the icon in a table you can make the table columns movable drag the points on the graph to watch the best fit line update. Correlation and regression calculator enter two data sets and this calculator will find the equation of the regression line and corelation coefficient. Home mathematics regression.
