Exponential Family

A family of PDFs with the general form of $P(x,\theta ,\varphi )=e^{\frac{\theta x-b(\theta )}{a(\varphi )}+c(x,\varphi )}$ where $\theta$ is the location parameter (or Expectation) and $\varphi$ is the dispersion parameter (or Variance)

Part of this family are:

• Normal Distribution
• Exponential Distribution
• Binomial Distribution
• Poisson Distribution
• Hypergeometric Distribution
