linear regression calculator y=mx+b

This critical value can also be found by using the TINV function in Excel. (Phew! A regression equation calculator uses the same mathematical expression to predict the results. Regression Calculator All you have A negative slope indicates that the line is going downhill. The prediction interval shows the range of y values that the model believes would occur for an x value. The formula for the best-fitting line (or regression line) is y = mx + b, where m is the slope of the line and b is the y-intercept. Statisticians call this technique for finding the best-fitting line a simple linear regression analysis using the least squares method. Use the F statistic to determine whether the observed relationship between the dependent and independent variables occurs by chance.

Choose the account you want to sign in with. In addition to using LOGEST to calculate statistics for other regression types, you can use LINEST to calculate a range of other regression types by entering functions of the x and y variables as the x and y series for LINEST.
