## Gamma Distribution

Gamma Distribution Gamma distribution is used to model a continuous random variable which takes positive values. Gamma distribution is widely used in science and engineering to model a skewed distribution. In this tutorial, we are going to discuss various important statistical properties of gamma distribution like graph of gamma distribution for various parameter combination, derivation …

## Continuous Uniform Distribution

Continuous Uniform Distribution Continuous uniform distribution is the simplest of all the distributions in statistics. The density function of continuous uniform distribution is flat like a rectangle, hence it is often called rectangular distribution. The probability is uniformly distributed in a closed interval $[\alpha,\beta]$. A continuous random variable $X$ is said to have a continuous …

## Geometric Distribution

Introduction Geometric distribution is used to model the situation where we are interested in finding the probability of number failures before first success or number of trials (attempts) to get first success in a repeated mutually independent Beronulli’s trials, each with probability of success $p$. There are two different definitions of geometric distributions one based …

## Poisson Distribution

Poisson Distribution Poisson distribution helps to describe the probability of occurrence of a number of events in some given time interval or in a specified region. The time interval may be of any length, such as a minutes, a day, a week etc. Definition of Poisson Distribution A discrete random variable $X$ is said to …
