Flood frequency analysis using method of moments and L-moments of probability distributions

open access: yesCogent Engineering, 2015
Estimation of maximum flood discharge (MFD) at a desired location on a river is important for planning, design and management of hydraulic structures. This can be achieved using deterministic models with extreme storm events or through frequency analysis

The variational method of moments

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2023
Abstract The conditional moment problem is a powerful formulation for describing structural causal parameters in terms of observables, a prominent example being instrumental variable regression. We introduce a very general class of estimators called the variational method of moments (VMM), motivated by a variational minimax reformulation

A New Quasi Poison-Lindley Distribution: Properties and Applications [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2017
A new two parameter quasi Poisson Lindley (NQPL) distribution is derived by using the general approach of compounding. One parameter Lindley distribution and geometric distribution may be obtained as a particular case. The new distribution is shown to be
