ARMA Modelling of Sleep Spindles [PDF]

open access: yes, 2011
Differences in EEG sleep spindles constitute a promising indicator of neurodegenerative disorders. In this paper an ARMA modelling to sleep spindles is proposed and tested. The primary objective is to distinguish, via poles and zeros location, between regular, elderly and dementia subjects.

Exact recursive least squares algorithms for ARMA modeling

open access: yes, 1987
The present paper aims to present an entirely new approach for the development of "exact" recursive least squares algorithms for ARMA filtering and modeling when the inputs (asssumed here to be "white") are not observable.

Monitoring Quality of Mafia‐Connected Accountants

open access: yesJournal of Accounting Research, EarlyView.
ABSTRACT We investigate the monitoring quality of accountants with ties to the Mafia in their role as auditors for “clean” firms—those with no known ties to organized crime. Using a proprietary government database, we identify Italian firms with alleged ties to the Mafia through their executives, directors, or shareholders.

Winners and losers in subarctic moth communities in a changing climate: Marine regime shifts as predictors for terrestrial insect biomass

open access: yesInsect Conservation and Diversity, EarlyView.
1972–2017, the total moth biomass ina subarctic community had a positive trend but biomass trends differ betweenmoth groups based on taxonomy, phenology and resource use. In the northern latitudes,outbreaking species impact greatly moth biomass Moth biomass is associated withtemperature variables and marine Regime shifts, which can be effective ...
