Tematy:: lifetime distribution

bathtub hazard
likelihood function
maximum likelihood estimation
Opis:: In this paper, we argue the necessity of dealing with lifetime distributions with wave-like bathtub hazard function. Four classes of wave-like bathtub hazards are investigated. For preparing maximum likelihood estimation of the hazard parameters, the first-order and second-order partial derivatives are derived.

Wydawca:: Główny Urząd Statystyczny
Tematy:: compound distribution
hazard rate function
lifetime distribution
maximum likelihood estimation
power series distribution
Opis:: We introduce a new generalized family of nonnegative continuous distributions by adding two extra parameters to a lifetime distribution, called the baseline distribution, by twice compounding a power series distribution. The new family, called the lifetime power series-power series family, has a serial arrangement of parallel structures, which extends the Marshall and Olkin structure. Four special models are discussed. A mathematical treatment of the new distributions is provided, including ordinary and incomplete moments, quantile, moment generating and mean residual functions. The maximum likelihood estimation technique is used to estimate the model parameters and a simulation study is conducted to investigate the performance of the maximum likelihood estimates. Its applicability is also illustrated by means of two real data sets.

Tytuł:: Binomial ARMA count series from renewal processes
Autorzy:: Koshkin, Sergiy
Cui, Yunwei
Powiązania:: https://bibliotekanauki.pl/articles/729904.pdf
Data publikacji:: 2012
Wydawca:: Uniwersytet Zielonogórski. Wydział Matematyki, Informatyki i Ekonometrii
Tematy:: integer-valued time series
stochastic difference equations
autoregressive moving average
renewal process
lifetime distribution
probability generating function
palindromic polynomial
constant hazard rate
Opis:: This paper describes a new method for generating stationary integer-valued time series from renewal processes. We prove that if the lifetime distribution of renewal processes is nonlattice and the probability generating function is rational, then the generated time series satisfy causal and invertible ARMA type stochastic difference equations. The result provides an easy method for generating integer-valued time series with ARMA type autocovariance functions. Examples of generating binomial ARMA(p,p-1) series from lifetime distributions with constant hazard rates after lag p are given as an illustration.
