Two-Parameter Rayleigh Distribution: Different Methods of Estimation

In this paper we have considered different methods of estimation of the unknown parameters of a two-parameter Rayleigh distribution both from the frequentists and Bayesian view points. First we briefly describe different frequentists approaches, namely maximum likelihood estimators, moments estimators, L-moment estimators, percentile based estimators and least squares estimators, and compare th...

Jacobi-Davidson methods for polynomial two-parameter eigenvalue problems

We propose Jacobi–Davidson type methods for polynomial two-parameter eigenvalue problems (PMEP). Such problems can be linearized as singular two-parameter eigenvalue problems, whose matrices are of dimension k(k + 1)n/2, where k is the degree of the polynomial and n is the size of the matrix coefficients in the PMEP. When k2n is relatively small, the problem can be solved numerically by computi...

Numerical Methods for Two-Parameter Local Bifurcation Analysis of Maps

We discuss new and improved algorithms for the bifurcation analysis of fixed points and periodic orbits (cycles) of maps and their implementation in matcont, a matlab toolbox for continuation and bifurcation analysis of dynamical systems. This includes the numerical continuation of fixed points of iterates of the map with one control parameter, detecting and locating their bifurcation points (i...

Parameter optimization for explicit parallel peer two-step methods

Due to a two-step structure certain explicit peer methods with s stages have a natural parallel implementation on s processors. By the peer property all stages have essentially identical properties and we construct a class of zerostable methods with order p = s in all stages. Two approaches are discussed for choosing the free parameters. In a certain subclass the stability polynomial depends on...
