Chi-squared distribution PDF — degrees of freedom, Matlab & Python examples
What a chi-squared distribution is, how degrees of freedom shape the PDF, and how to sample/plot it in Matlab or Python — used in energy detection and confidence regions.
Uniform random variable
Uniform random variables are used to model scenarios where the expected outcomes are equi-probable. For example, in a communication system design, the set of all possible source symbols are considered equally probable and therefore modeled as a uniform random variable. The uniform distribution is the underlying distribution for an uniform random variable. A continuous uniform … Read more
