Probability distribution functions (PDFs) describe the expected values of random variables drawn from a sample. The shape of the PDF explains how likely it is that an observed value might occur.

In a number of situations we are faced with the problem of determining efficient estimates of the mean and variance of a distribution specified by (i) a non-zero probability that the variable assumes ...

Boyan Dimitrov, Stefanka Chukova, David Green, Jr. Periodic random environments and mechanisms of their effect on imbedded random variables are discussed. The variables under consideration represent ...

By using one of the common stock probability distribution methods of statistical calculations, an investor may determine the likelihood of profits from a holding.

Resources Calculating probabilities on a Poisson distribution: Poisson Distribution Calculator This web calculator allows users to specify the Poisson parameter (λ) and number of occurrences (x).

You can use the RAND () function to establish probability and create a random variable with normal distribution.
