LQ-Moments: Application to the Log-Normal distribution [PDF]

Journal of Mathematics and Statistics, 2006
Summary: \textit{G. S. Mudolkar} and \textit{A. D. Hutson} [J. Stat. Plann. Inference 71, No.~1--2, 191--208 (1998; Zbl 0981.62039)] extended L-moments to new moments called LQ-moments (LQMOM). The LQMOM are constructed by using functionals defining quick estimators, where the parameters of quick estimators take the values \(p = 0\), \(\alpha = 1\) for

The A Priori Procedure for Estimating the Mean in Both Log-Normal and Gamma Populations and Robustness for Assumption Violations

Methodology, 2022
Although the literature on the a priori procedure, designed to help researchers determine the sample sizes they should use in their substantive research, is expanding rapidly, there are two important limitations.

Investigating the Effect of Distribution Function and Potential Evapotranspiration Assessment Method in Determining Reconnaissance Drought Index [PDF]

علوم و مهندسی آبیاری, 1970
Iran is located in arid and semi-arid regions in the world and therefore, drought monitoring has an important role in there. Drought assessment is conventionally based on drought indices such as Reconnaissance Drought Index (RDI).

Discriminating between the Weibull and log‐normal distributions [PDF]

Naval Research Logistics (NRL), 2004
AbstractLog‐normal and Weibull distributions are the most popular distributions for modeling skewed data. In this paper, we consider the ratio of the maximized likelihood in choosing between the two distributions. The asymptotic distribution of the logarithm of the maximized likelihood ratio has been obtained.

Model misspecification of Log-Normal and Birnbaum-Saunders distributions

Communications in Statistics - Simulation and Computation, 2022
Abstract Model misspecification can be a serious issue in any lifetime data analysis. Assumption of the correct model is very important particularly in prediction for future observations and for estimating the tail probabilities of any lifetime distribution.

An Alternative to the Log-Skew-Normal Distribution: Properties, Inference, and an Application to Air Pollutant Concentrations

Mathematics, 2022
In this study, we consider an alternative to the log-skew-normal distribution. It is called the modified log-skew-normal distribution and introduces greater flexibility in the skewness and kurtosis parameters.

Maximum discharge and probable rainfall at Aiuruoca basin, Minas Gerais State

Revista Ambiente & Água, 2014
Research on rainfall and annual daily maximum discharge rates is essential to support decisions during the design of hydraulic structures. This study tested the adequacy of probability functions to predict the probable rainfall and discharge rates of the

Measurable Residual Disease Monitoring During Treatment for Pediatric Acute Myeloid Leukemia in First Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.
