Weighted Compositions [PDF]

open access: yesCanadian Mathematical Bulletin, 1961
By a composition of a positive integer n is meant a representation of n as a sum of one or more positive integers where the order of the summands is taken into account. Thus for example 4 has the eight compositions 4 = 3 + 1 = 1 +3 = 2 + 2 = 2 + 1 + 1 = 1 + 2 + 1 = 1 + 1 + 2 = 1 + 1 + 1 + 1.

To Weight or Not to Weight, That Is the Question: The Design of a Composite Indicator of Landscape Fragmentation

open access: yesApplied Sciences, 2021
Composite indicators (CIs), i.e., combinations of many indicators in a unique synthetizing measure, are useful for disentangling multisector phenomena. Prominent questions concern indicators’ weighting, which implies time-consuming activities and should ...

A Note on the Conditioning of the H−1 Matrix Used in Single-Step GBLUP

open access: yesAnimals, 2022
The single-step genomic BLUP (ssGBLUP) is used worldwide for the simultaneous genetic evaluation of genotyped and non-genotyped animals. It is easily extendible to all BLUP models by replacing the pedigree-based additive genetic relationship matrix (A ...

Reduced global warming from CMIP6 projections when weighting models by performance and independence

open access: yesEarth System Dynamics, 2020
To extract reliable estimates of future warming and related uncertainties from multi model ensembles such as CMIP6, the spread in their projections is often translated into probabilistic estimates such as the mean and likely range.
