Location-scale family
Witryna1 dzień temu · For any distribution function f(x), a family of distribution functions, indexed by the parameters μ (the location parameter) and σ (the scale parameter), of the form (1/σ)f(x − μ)/σ).An example is the normal family: a normal distribution with mean μ and variance σ 2 can be obtained from the standard normal distribution by stretching (σ > … In probability theory, especially in mathematical statistics, a location–scale family is a family of probability distributions parametrized by a location parameter and a non-negative scale parameter. For any random variable $${\displaystyle X}$$ whose probability distribution function belongs to such a family, the … Zobacz więcej Often, location–scale families are restricted to those where all members have the same functional form.

Witryna3 wrz 2024 · A scale family of distributions has densities of the form. g ( x θ) = 1 θ ⋅ ψ ( x θ) ( 1) where θ > 0 and ψ is a density. Now let's take the pdf of an exponential rv. f X ( x) = 1 θ e − x / θ. It is immediate to recognize that f X ( x) is in the form (1) where ψ = e − y is the density of a negative exponential rv with mean 1. WitrynaReturns an object of class "gamlss", which is a generalized additive model for location scale and shape (GAMLSS). The function gamlss () is very similar to the gam () function in S-plus (now also in R in package gam ), but can fit more distributions (not only the ones belonging to the exponential family) and can model all the parameters of the ...
