Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points.
Fitted curves can be used as an aid for data visualization, to conclude values of a function where no data are available, and to summarize the relationships among two or more variables.
Equation for Exponential Decay Curve is, Y = \frac { 1 }{ B } .{ e }^{ \left( \frac { { A-x } }{ B }
ight) } Where A is Position,
B is Scale parameter
Similarly Equation for Exponential Increase Curve is, Y = \frac { 1 }{ B } .{ e }^{ \left( \frac { { A+x } }{ B }
ight) }

[@martinlintzgy1361]

thank you. This gives a much better fit than the built in exponential trendline

[@hayleymcmillan7581]

Super helpful. Thank you!

[@fajiechen7305]

Thank you very much for the video. This method gives a good fitting. Btw, is there anyway to show R squared by this method?

[@gototcm]

Excellent. Forgot how to do this and you helped refresh my old, fading memory.

Hi. Why is it that in 06:44 Excel finds that (B2 - C2)^2 = 2 when it should be (4 - 3)^2 = 1?

[@VijayPatil-ur5bz]

Thanks a lot for the video. Can you provide any reference to this method for verification purposes? I need to provide evidence along with the application of this method

[@jatinSharma-qu4xl]

What will be the equation for negative exponential curve?

[@mxcripto8040]

Great video. For some reason my solver does not work and I was not able to solve my problem. I tried with your data and it didn't solve either. I had to manually vary A and B to get a somewhat good fit. I'm getting almost .2% error between predicted and actual, so not too bad for my application. THANKS A LOT!

Glad it helped
