Understand

This paper is a step-by-step tutorial for fitting a mixture distribution to data.

It merely assumes the reader has the background of calculus and linear algebra.
Other required background is briefly reviewed before explaining the main algorithm.
In explaining the main algorithm, first, fitting a mixture of two distributions is detailed and examples of fitting two Gaussians and Poissons, respectively for continuous and discrete cases, are introduced.
