Estimating Parameters of Gumbel Distribution using the Methods of Moments, probability weighted Moments and maximum likelihood
Estimating Parameters of Gumbel Distribution using the Methods of Moments, probability weighted Moments and maximum likelihood
(2012-03-02)
We derive here estimators for the parameters of the Gumbel distribution using three estimating methods, namely, the probability weighted moments, the moment and the maximum likelihood methods. Furthermore, we compare the ...

The goal of our on-going research is to develop effective and reliable tools formodeling the environmental systems of the Gulf of Mexico. For example, our on-goingresearch into methodologies for the prediction of water ...
One-Sided Confidence Interval Estimation for Weibull Shape and Scale Parameters
One-Sided Confidence Interval Estimation for Weibull Shape and Scale Parameters
(2012-03-02)
In this paper, we consider the problem of one-sided conditional and unconditional interval estimation for the scale and shape parameters in a two-parameter Weibull model. The statistical inference is based upon the pivots ...

Scattering of e Polarized Whispering-Gallery mode from Concave Boundary
(2012-03-01)
In this work we present numerical results for the 2D problem of scattering E polarised whispering-gallery mode from concave convex perfectly conducting boundary. The results were obtained by applying the developed method ...
¿Como Trabajan las Calculadoras?
