WitrynaGeneralized Additive Models for Location Scale and Shape ... The distribution for the response variable in the GAMLSS can be selected from a very general family of distributions including highly skew and/or kurtotic continuous and discrete distributions, see gamlss.family.

Location–scale family - Wikiwand

Witryna21 lis 2024 · We consider stochastic comparisons of minimum order statistics from the location–scale family of distributions that contain most of the popular lifetime distributions. Under certain assumptions, we show that the minimum order statistic of one set of random variables dominates that of another set of random variables with … 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.
