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

Three-parameter lognormal distribution: parametric estimation using l-moment and tl-moment approach [PDF]

open access: yes, 2016
The three-parameter lognormal (LN3) distribution has been applied to the frequency analysis of flood events. L-moment and TL-moment methods are applied in estimating parameters of the LN3 distribution which are L-moment, η = 0 and TL-moment, η = 1, 2, 3,

Penggunaan gambar rajah nisbah LQ-momen dalam pemilihan taburan terbaik [PDF]

open access: yes, 2010
The method of moments has been one of the simplest and conventional parameter estimation techniques used in statistical hydrology. However, moment estimates are usually inferior in quality and generally not as efficient as the L-moment estimates ...

TL-Moments: Analogy of Classical L-Moments [PDF]

open access: yesInternational Scientific Conference, 2014
Moments and cumulants are commonly used to characterize the probability distribution or observed data set. The use of the moment method of parameter estimation is also common in the construction of an appropriate parametric distribution for a certain data set. The moment method does not always produce satisfactory results.

Characterisation of global precipitation frequency through the L‐moments approach

open access: yesArea, 2012
Higher‐order statistics, such as skewness and kurtosis, are useful measures to describe the shape of a probability distribution. In hydrology, the assessment of these parameters is an important step for representing precipitation frequencies and understanding rainfall variability.

A New Methodology for Estimating Internal Credit Risk and Bankruptcy Prediction under Basel II Regime

open access: yes, 2014
Credit estimation and bankruptcy prediction methods have been utilizing Altman's $z$ score method for the last several years. It is reported in many studies that $z$ score is sensitive to changes in accounting figures.

A nonlinear random walk approach to concentration-dependent contaminant transport in porous media [PDF]

open access: yes, 2009
We propose a nonlinear random walk model to describe the dynamics of dense contaminant plumes in porous media. A coupling between concentration and velocity fields is found, so that transport displays non-Fickian features. The qualitative behavior of the

Simulating Burr Type VII Distributions through the Method of L-moments and L-correlations [PDF]

open access: yes, 2014
Burr Type VII, a one-parameter non-normal distribution, is among the less studied distributions, especially, in the contexts of statistical modeling and simulation studies.

Statistical Analysis of COVID-19 Data: Using A New Univariate and Bivariate Statistical Model

open access: yesJournal of Function Spaces, 2022
In this paper, a new distribution named as unit-power Weibull distribution (UPWD) defined on interval (0,1) is introduced using an appropriate transformation to the positive random variable of the Weibull distribution. This work offers quantile function,

Regional Frequency Analysis for Rainfall using L-Moment [PDF]

open access: yesThe Journal of the Korea Contents Association, 2008
This study was conducted to derive the optimal regionalization of the precipitation data which can be classified on the basis of climatologically and geographically homogeneous regions all over the regions except Cheju and Ulreung islands in Korea. A total of 65 rain gauges were used to regional analysis of precipitation.
