On new tests for the Poisson distribution based on empirical weight functions
Winnie Kirui, Elzanie Bothma, Marius Smuts +2
We propose new goodness-of-fit tests for the Poisson distribution. The testing procedure entails fitting a weighted Poisson distribution, which has the Poisson as a special case, t…
New classes of tests for the Weibull distribution using Stein's method in the presence of random right censoring
E Bothma, JS Allison, IJH Visagie
We develop two new classes of tests for the Weibull distribution based on Stein's method. The proposed tests are applied in the full sample case as well as in the framework of rand…
Kaplan-Meier based tests for exponentiality in the presence of censoring
E. Bothma, J. S. Allison, M. Cockeran +1
In this paper we test the composite hypothesis that lifetimes follow an exponential distribution based on observed randomly right censored data. Testing this hypothesis is complica…
On the conditional distribution of the mean of the two closest among a set of three observations
I. J. H. Visagie, F. Lombard
Chemical analyses of raw materials are often repeated in duplicate or triplicate. The assay values obtained are then combined using a predetermined formula to obtain an estimate of…
