    Comparing Distributions of Datasets

    I've been asked to find a method to best compare the distribution of a number datasets that have small sample sizes. Bonus points for a solution/result that is in a scale of 0-1, i.e. a distribution approaching 1 is bordering on perfectly unequal and a distribution approaching 0 is bordering on...

    Generalization of urn problem

    While simple urn problems - given x green and y black balls, whats the probability if we take 6 that 2 will be black etc. are easily solvable with hypergeometric and binomial distribution. Is there a distribution that solves it a general case for example: Given 1000 blue, 1200 green, 2000 red...

    Estimating the Average and Standard Deviation with Missing Data

    I need a way to shows me how the parameters of PDF, log-normal in this case, can be estimated based on a set with missing data points at the tail end of a sample. For example, Consider we had 20 numbers with specified μ and σ, and then missed two largest number of them. How do we can estimate...
