goodness-of-fit testing
Opis:: A modified version of Bagdonavičius-Nikulin goodness-of-fit statistical test is presented for validation under the right censor case. Simulation via Barzilai-Borwein algorithm is performed for assessing the right-censorship estimation method. Four right censored data sets are analyzed under the new modified test statistic for checking the distributional validation.

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

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.

Tytuł:: A Two-Parameter Lindley Distribution
Autorzy:: Shanker, R.
Mishra, A.
Powiązania:: https://bibliotekanauki.pl/articles/465861.pdf
Data publikacji:: 2013
Wydawca:: Główny Urząd Statystyczny
Tematy:: Lindley distribution
moments
failure rate function
mean residual life function
stochastic ordering
estimation of parameters
goodness of fit
Opis:: A two-parameter Lindley distribution, of which the Lindley distribution (LD) is a particular case, has been introduced. Its moments, failure rate function, mean residual life function and stochastic orderings have been discussed. The maximum likelihood method and the method of moments have been discussed for estimating its parameters. The distribution has been fitted to some data-sets to test its goodness of fit.

Tytuł:: A New Quasi Sujatha Distribution
Autorzy:: Shanker, Rama
Shukla, Kamlesh Kumar
Powiązania:: https://bibliotekanauki.pl/articles/1058938.pdf
Data publikacji:: 2020-09-04
Wydawca:: Główny Urząd Statystyczny
Tematy:: Sujatha distribution
quasi Sujatha distribution
moments
reliability properties
stochastic ordering
stress-strength reliability
estimation of parameters
goodness of fit
Opis:: The aim of this paper is to introduce a new quasi Sujatha distribution (NQSD), of which the following are particular cases: the Sujatha distribution devised by Shanker (2016 a), the sizebiased Lindley distribution, and the exponential distribution. Its moments and momentsbased measures are derived and discussed. Statistical properties, including the hazard rate and mean residual life functions, stochastic ordering, mean deviations, Bonferroni and Lorenz curves and stress-strength reliability are also analysed. The method of moments and the method of maximum likelihood estimations is discussed for estimating parameters of the proposed distribution. A numerical example is presented to test its goodness of fit, which is then compared with other one-parameter and two-parameter lifetime distributions.
