The thing about statistics is that beyond a point of learning where you have learned and codified all knowledge and understanding, there is a need to maintain a compendium. Sometimes, it’s good to remind yourselves of all the tools available and not just the hammers (read Deep Learning). The source code is embedded in the Title itself.

Central Limit Theorem

Central limit theorem states that if you sample sufficient number of samples from a distribution, albeit any kind of distribution and take their means. This process when repeated for multiple iterations, the means will follow a normal distribution.

The below histogram is generated using means generated from a poisson distribution with same mean as above normal distribution. Poisson has same standard deviation as mean value
