Get PriceThis question was asked more than 3 years ago, so I hope my answer doesn't come too late. There is a way to uniquely identify a distribution when knowing some of the moments. That way is the method of Maximum Entropy.The distribution that results from this method is the distribution that maximizes your ignorance about the structure of the distribution, given what you know.

Here, we have our first discrete distribution, called the Poisson distribution. And this comes up in HCI and interaction design studies a lot.

Get PriceA probability distribution describes how the values of a random variable is distributed. For example, the collection of all possible outcomes of a sequence of coin tossing is known to follow the binomial distribution.Whereas the means of sufficiently large samples of a data population are known to resemble the normal distribution.Since the characteristics of these theoretical distributions are

Get PriceIn statistics, the concept of the shape of a probability distribution arises in questions of finding an appropriate distribution to use to model the statistical properties of a population, given a sample from that population. The shape of a distribution may be considered either descriptively, using terms such as "J-shaped", or numerically, using quantitative measures such as skewness and kurtosis.
