Extremes of solar spectral irradiance in the SORCE/XPS record
Enzo Brasil, Cira E. G. Otiniano, Carolyne Brito +2
Extreme and rare changes in space mission solar irradiance records are scientifically relevant but difficult to quantify because these records are finite, instrument dependent, and…
Joint return levels of maximum temperature and minimum relative humidity by combining copulas with an extreme value framework for bimodal data
Beatriz G da Cruz Albernaz, Cira E G Otiniano, Carolyne Soares de Brito +2
Climate change has become a growing concern, particularly in regions experiencing increasingly frequent extreme events. In Brasília, the capital of Brazil, significant shifts in cl…
Conditional copula representations and extremal bounds for multivariate statistical functionals
Roberto Vila, Cira E G Otiniano, Carolyne Brito +1
In this paper, we derive a conditional copula representation for expectations of the form , where is a random vector with arbitrary…
Multiple Imputation Methods under Extreme Values
Enzo Porto Brasil
Missing data are ubiquitous in empirical databases, yet statistical analyses typically require complete data matrices. Multiple imputation offers a principled solution for filling…
