Curve fitting excel exponential. The basic statistical information returned is the array of constants m n m n 1. Exponential smoothing forecast excel 2016 data analysis toolpak duration. The exponential function y c exp b x is useful for fitting some non linear single bulge data patterns. A logarithmic function has the form.

Fitting a logarithmic curve to data. The excel logest function returns statistical information on the exponential curve of best fit through a supplied set of x and y values. Curve is then expected to have the minimum value of 2 i i χ. A similar technique can be used for exponential logarithmic and power function curve fitting in excel as well.

Excel has a preprogrammed feature that will find the best fitting equation for a data set for a select number of functions. Instead we will focus on using excel to produce a best fitting curve of the appropriate model. We can still use linest to find the coefficient m and constant b for this equation by inserting ln x as the argument for the known x s. We can use the fisolverfl add in in excel to find the values of a c and k that result in the minimum value for 2 i i χ cell g4 procedure to fit the data 1.
