Hello All,
I once asked before this topic as well, but could not solve the problem.
Please guide me that how can I show this graph in mathematical equation form ?
Or taking these points, can we make a mathematical relation.
thank you very much for your time.
Best regards.
Among a few others, this software can be the solution of your problem: http://www.palisade-europe.com/bestfit/
It is very popular in simulation analysis.
One thing you can do is try least squares fitting of sums of distributions. Here's an example of sum of 3 distributions. Using 1 or 2 distributions will result in a smoother curve but further from the data points.
Looks like a nice package suggested by Rassis.

Get a graphing calculator, add the points and find a regression formula that fits your data best (you have choices like sin, linear, quad, quartic, power, etc). Higher power regression formulas usually yield a close correlation value (hence a better fit).
