Species traits shape the relationship between local and regional species abundance distributions

open access: yesEcosphere, 2019
The species abundance distribution (SAD) depicts the relative abundance of species within a community, which is a key concept in ecology. Here, we test whether SADs are more likely to either follow a lognormal‐like or follow a logseries‐like distribution

Finding Most Reliable Path With Extended Shifted Lognormal Distribution

open access: yesIEEE Access, 2018
Travel time uncertainty may cause late arrival and impose a high penalty on travelers. There is a growing interest in modeling travel time uncertainty to optimize the reliability of travel time at the path and network level. Real data analysis finds that

Goodbye LogNormal Distribution

open access: yes, 2022
AbstractThe R-scripts presented and developed in the prior chapters assumed an investment return generating process that is both static and LogNormal, via the basic function. Indeed, had this work been done in the 1970s, or perhaps the 1670s when national (versus natural) tontines were first launched, that might have been sufficient.
