Truncating the exponential with a uniform distribution
Weißbach, Rafael; Wied, Dominik - In: Statistical Papers 63 (2021) 4, pp. 1247-1270
For a sample of Exponentially distributed durations we aim at point estimation and a confidence interval for its parameter. A duration is only observed if it has ended within a certain time interval, determined by a Uniform distribution. Hence, the data is a truncated empirical process that we...

Maximum product of spacings prediction of future record values
Volovskiy, Grigoriy; Kamps, Udo - In: Metrika 83 (2020) 7, pp. 853-868
A spacings-based prediction method for future upper record values is proposed as an alternative to maximum likelihood … prediction. For an underlying family of distributions with continuous cumulative distribution functions, the general form of the … the maximum observed likelihood prediction procedure is shown. The maximum product of spacings predictor turns out to be …

Generalized Ng–Kundu–Chan model of adaptive progressive Type‐II censoring and related inference
Schmiedt, Anja Bettina; Cramer, Erhard - In: Naval Research Logistics (NRL) 71 (2023) 3, pp. 389-415
The model of adaptive progressive Type-II censoring introduced by Ng et al. (2009)(referred to as Ng–Kundu–Chan model) is extended to allow switching from a given initial censoring plan ℛ to any arbitrary given plan 𝒮 of the same length. In this generalized model, the joint distribution...

Analyzing firm mortality using life table techniques
Pflaumer, Peter - 1994
The mortality of German joint stock companies is investigated using life table techniques. An EDB-distribution or Hjorth-distribution and an exponential distribution are fitted to the hazard rates, whereby the population is divided into small and large firms. Survivor functions and life...

Strategic Experimentation with Exponential Bandits
Cripps, Martin; Keller, Godfrey; Rady, Sven - 2003
This paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a payoff only after some exponentially distributed random time. Because of free-riding, there is an inefficiently low level of experimentation in any equilibrium where the players use...

Negatively Correlated Bandits
Klein, Nicolas; Rady, Sven - 2008
We analyze a two-player game of strategic experimentation with two-armed bandits. Each player has to decide in continuous time whether to use a safe arm with a known payoff or a risky arm whose likelihood of delivering payoffs is initially unknown. The quality of the risky arms is perfectly...

Conditional moment tests for parametric duration models
Prieger, James E. - 2000
This paper develops and compares specification tests for parametric duration models estimated with censored data. The tests are based on generalized residuals (the integrated hazard), which is exponentially distributed if the model is correctly specified. I present several conditional moment...

Stage life testing
Laumen, Benjamin; Cramer, Erhard - In: Naval Research Logistics (NRL) 66 (2019) 8, pp. 632-647
In progressive censoring, items are removed at certain times during the life test. Commonly, it is assumed that the removed items are used for further testing. In order to take into account information about these additional testing in inferential procedures, we propose a two-step model of stage...

Investigating the exponentialage distribution of firms
Coad, Alexander - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2009
While several plots of the aggregate age distribution suggest that rm age is expo-finentially distributed, we find some departures from the exponential benchmark. At thelower tail, we find that very young establishments are more numerous than expected,but they face high exit hazards. At the...
