Review of Basic Statistical Concepts
... Models: In order to use statistical inference or form confidence intervals, we need to have a model for our random variable. In the present context, this means we assume that the random variable has a certain (type of) distribution. Just what model (distribution)we choose depends on what we know abo ...

Basics of the Probability Theory
... Suppose we want to generate uniform random points inside a circle of radius ρ and centered at the origin. We can represent the location of such a point as R(cos Θ, sin Θ), where R and Θ are two random variables with ranges [0, ρ] and [0, 2π], respectively. The value of Θ follows the uniform distribu ...
