In comparison, all of the other types of trendlines that Excel produces match the data fairly well. An exponential function has the form: It’s a little trickier to get the coefficients, a and b, for this equation because first we need to do a little algebra to make the equation take on a linear form. The purple graph represents the Exponential Regression Model for the set of data (y2). Problem: It's clear to me just by looking at the graph that the exponential trendline does not match the data. Bidvest Facilities Management, a member of the Bidvest Group, is an industry leader in South Africa, with extensive technical capabilities and a national footprint. Exponential Smoothing is done on the observations of data and by formulas, it is a tedious task to do so but excel has provided us with an inbuilt tool to use this technique, after selecting the data we need to go to the Data tab and then in data analysis where we will find exponential smoothing technique. The black line is a regression trendline that has been auto-generated by Excel.
