A Parametric Model for the Interval Censored Survival Times of Acacia Mangium Plantation in a Spacing Trial

Kudus, Kamziah Abd; Kimber, A. C.; Lapongan, J. - In: Journal of Applied Statistics 33 (2006) 10, pp. 1067-1074

Survival times for the Acacia mangium plantation in the Segaliud Lokan Project, Sabah, East Malaysia were analysed based on 20 permanent sample plots (PSPs) established in 1988 as a spacing experiment. The PSPs were established following a complete randomized block design with five levels of...

Modelling memory processes and Internet response times: Weibull or power-law?

Chessa, Antonio G.; Murre, Jaap M.J. - In: Physica A: Statistical Mechanics and its Applications 366 (2006) C, pp. 539-551

The Weibull distribution is proposed as a model for response times. Theoretical support is offered by classical results … for extreme-value distributions. Fits of the Weibull distribution to response time data in different contexts show that …

International inflationary episodes: a survival analysis

Ali AbderrezakAuthor-Email: aabderre@jccc.edu - In: Journal of Developing Areas 40 (2006) 1, pp. 141-153

Instances of acute and sustained inflation pose a challenge in transition and developing economies, in particular as they tend to render economic development strategies vulnerable. Thus, a thorough understanding of inflationary episodes is critical. Using parametric hazard models, this examines...

Robust 2k factorial design with Weibull error distributions

Bi-super-˙rdal Senoğlu - In: Journal of Applied Statistics 32 (2005) 10, pp. 1051-1066

It is well known that the least squares method is optimal only if the error distributions are normally distributed. However, in practice, non-normal distributions are more prevalent. If the error terms have a non-normal distribution, then the efficiency of least squares estimates and tests is...
