The more close the value is to 1 the more accurate the model is. Press ENTER twice and the exponential regression program will be run. As a result we get an equation of the form y a b x where a 0.
Enter y1 y 1 abx1 a b x 1 in the next line.
Code to add this calci to your website The exponential fit can be calculated using the exponential least square fittings method. Delete a variable with a high P-value greater than 005 and rerun the regression until Significance F drops below 005. And thinking up quite a different model. You need to use expmod.
