Could anyone explain in laymen terms what really the beta function does as said in Beta Function:https://en.wikipedia.org/wiki/Beta_function .I know that gamma function is used to find the factorial of real numbers but when it comes to beta function I can't get what really beta function does.I am reading an article: Empirical Analysis:http://1drv.ms/1GUqmdO:and it explains about Dirichlet distribution:https://en.wikipedia.org/wiki/Dirichlet_distribution(adsbygoogle = window.adsbygoogle || []).push({});

After looking for the prerequisites needed to study Dirichlet distribution as said in Prerequisites for Dirichlet distribution:http://www.metacademy.org/graphs/concepts/dirichlet_distribution#focus=5zwsgm7z&mode=explore I have reached up to Beta distribution:https://en.wikipedia.org/wiki/Beta_distribution in the tree.This is where the beta function comes in beta distribution and that's where I'm stuck.Could anyone help me.

I would like an answer that doesn't uses too much symbols,concepts and jargon terms.I would like a simple explanation for Beta function and how it is used in Beta distribution.
