Comment on Intuitive Bass Diffusion by acasoanalytics

Hi Emily, we could assume that the form is the same as the bass diffusion curve and perform a least squares fit to find the parameters that best describe the data. If you email the data set to me I can try this quickly.

Hey Billy
I was given a set of numbers that were generated through a complicated set of steps for an S curve and I am supposed to find a formula that would hold on one line. I have not been given the parameters of the curve, just the resulting points on the curve (23 points). Do you know how I can find this formula?

Alan Davies on the exact same problem (see link below). I always favour the “changing your mind swaps from win to lose or vice versa so you should always change” explanation. Except for that Excel spreadsheet approach…

Absolutley brilliant! I had a great time reading the thread. I sent it to everyone in work and within a minute we were having some heated debate

I love this problem for the fact that it never fails to get people worked up. Recently, Coding Horror had a post on a related problem, and the amount of comments (and flaming) that followed was pretty spectacular:

The 1000 cubes argument is a nice one! I’ll try it next time I explain someone why “they are all wrong”…

Hi, your right, the original formulation is a bit of a pain. There was a good post that rephrased the diffusion curve in terms of sensible numbers. There is a link to the interactive model here http://acasoanalytics.wordpress.com/2008/07/04/intuitive-bass-diffusionintuitive-bass-diffusion/ this has a link to the original posting and explanation by Mathias.

One thing I still can’t figure out is WHAT units are defined by time. So I can make my S curve work, but is the time periods days, week, months, years, decades. Or do I also have to figure out WHEN penetration will have occurred, and back out from there. eg using the famous .03 and .38 share doesn’t go up much after time units hit 20. So if really I thought market will be saturated in five years, then I just relabel my time axis? Sorry to be so dense about this, but it seems that understanding the timing of this, is as important as the peak, and I don’t know how to get my arms around thinking about the units other than to throw out the whole equation and just consider the shape. Any thoughts here? Thanks!

Great quotes, thank you! I had forgotten how good Descartes was. And the Galileo quote is nicely relevant to software development.
