Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

European Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

Regularization Approaches for High‐Dimensional Cox Models: A Case Study in Triple‐Negative Breast Cancer

International Statistical Review, EarlyView.
Summary In high‐dimensional survival analysis, effective variable selection is crucial both for model interpretation and predictive performance. This paper investigates Cox regression with lasso and adaptive lasso penalties in genomic datasets where covariates far outnumber observations.

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

A New Extention of the Odd Inverse Weibull-G Family of Distributions: Bayesian and Non-Bayesian Estimation with Engineering Applications

Computational Journal of Mathematical and Statistical Sciences
In this work, we propose a novel generator called the "extended odd inverse Weibull-generator" to obtain better distribution flexibility. This generator is considered as a generalization of the three well-known families.

Extreme Polyploidy Reveals Functional Trade‐Offs in Plant Drought Responses

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyploidy shapes plant physiology and anatomy, yet the extent to which different ploidy levels influence drought responses remains unclear. Here, we investigated how ploidy affects cell‐level coordination and functional traits associated with water transport and retention.

On the Weibull distribution

, 1976
This work involves the comparisons of various estimates of the parameters of the Weibull distribution. These estimates have been obtained by using various statistical techniques, such as the method of maximum likelihood estimation, the method of moments,

A Novel Entropy‐Transformed Inverse Weibull Distribution: Development, Properties, and Application in Diverse Data Modeling

Engineering Reports
Standard distributions must be improved to enhance their capacity for data modeling because they do not inherently suit all sorts of data sets in an acceptable manner.

The Beta Generalized Inverse Weibull Distribution

British Journal of Mathematics & Computer Science, 2014
The beta generalized inverse Weibull distribution (BGIW) is suggested in this paper. The mathematical properties of the BGIW distribution are provided and the expression for the moment generating function is derived. Also, the analytical shapes of the corresponding probability density function, reliability function, hazard rate function, and mode are ...
