Tytuł:: The Weibull lifetime model with randomised failure-free time
Autorzy:: Sulewski, Piotr
Szymkowiak, Magdalena
Powiązania:: https://bibliotekanauki.pl/articles/2156948.pdf
Data publikacji:: 2022-12-15
Wydawca:: Główny Urząd Statystyczny
Tematy:: Weibull lifetime model
randomised failure-free time
compound Weibull distributions
Opis:: The paper shows that treating failure-free time in the three-parameter Weibull distribution not a constant, but as a random variable makes the resulting distribution much more flexible at the expense of only one additional parameter.

Tytuł:: Generalized extended Marshall-Olkin family of lifetime distributions

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:: Sujatha Distribution and its Applications
Autorzy:: Shanker, Rama
Powiązania:: https://bibliotekanauki.pl/articles/465746.pdf
Data publikacji:: 2016
Wydawca:: Główny Urząd Statystyczny
Tematy:: lifetime distributions
Akash distribution
Shanker distribution
Lindley distribution
mathematical and statistical properties
estimation of parameter
goodness of fit
Opis:: In this paper a new one-parameter lifetime distribution named “Sujatha Distribution” with an increasing hazard rate for modelling lifetime data has been suggested. Its first four moments about origin and moments about mean have been obtained and expressions for coefficient of variation, skewness, kurtosis and index of dispersion have been given. Various mathematical and statistical properties of the proposed distribution including its hazard rate function, mean residual life function, stochastic ordering, mean deviations, Bonferroni and Lorenz curves, and stress-strength reliability have been discussed. Estimation of its parameter has been discussed using the method of maximum likelihood and the method of moments. The applications and goodness of fit of the distribution have been discussed with three real lifetime data sets and the fit has been compared with one-parameter lifetime distributions including Akash, Shanker, Lindley and exponential distributions.
