New lifetime Shanker Weibull distribution: Structure and Properties

Ibn Al-Haitham Journal for Pure and Applied Sciences
This paper introduces a new model with two parameters titled “Shanker Weibull distribution". This distribution is obtained by merging the Shanker distribution with a scale of one parameter and the Weibull distribution with a shape parameter.

Using Quantile Regression for Duration Analysis [PDF]

Quantile regression methods are emerging as a popular technique in econometrics and biometrics for exploring the distribution of duration data. This paper discusses quantile regression for duration analysis allowing for a flexible specification of the ...

A new extension of generalized beta distribution: statistical properties, prediction estimation and application in failure components and physics data

Scientific African
This study presents a generalized function of the beta distribution combined with the gamma distribution, resulting in the compound generalized beta (CG-Beta) distribution.

Censored Quantile Regression Redux [PDF]

Quantile regression for censored survival (duration) data offers a more flexible alternative to the Cox proportional hazard model for some applications. We describe three estimation methods for such applications that have been recently incorporated into ...

Simple nonparametric estimators for unemployment duration analysis [PDF]

"We consider an extension of conventional univariate Kaplan-Meier type estimators for the hazard rate and the survivor function to multivariate censored data with a censored random regressor.

WAGE DISTRIBUTION IN SPAIN, 1994-1999: AN APPLICATION OF A FLEXIBLE ESTIMATOR OF CONDITIONAL DISTRIBUTIONS [PDF]

To investigate the trends in wages in Spain in 1994-1999, we propose a flexible estimator of conditional distributions. The estimator, based on a piecewise-linear specification of the conditional hazard function, allows us to capture almost any ...

Job seeker's allowance in Great Britain: How does the regional labour market affect the duration until job finding? [PDF]

Employing a large individual-level administrative dataset from Great Britain, covering the period 1999-2007, we analyse the factors influencing the length of unemployment benefits claimant periods with subsequent transition to re-employment. To this end,

Censored Quantile Regressions and the Length of Unemployment Periods in West Germany [PDF]

We apply censored quantile regressions to representative German register data with more than 91,000 observations in order to determine crucial factors that influence the distribution of unemployment duration in West Germany during the 1980s and 1990s. We
