WebMar 13, 2024 · Notation. Throughout this vignette, we denote values of the response variable as \(y\), a density function as \(f\), and use \(\mu\) to refer to the main model parameter, which is usually the mean of the response distribution or some closely related quantity. In a regression framework, \(\mu\) is not estimated directly but computed as \(\mu = … WebThe Rayleigh distribution arises as the distribution of the square root of an exponentially distributed (or \chi^2_2 χ22 -distributed) random variable.
