Are Characteristics Covariances or Characteristics?

SSRN Electronic Journal, 2020
In this article, we shed more light on the covariances versus characteristics debate by investigating the explanatory power of the instrumented principal component analysis (IPCA), recently proposed by Kelly et al. (2019). They conclude that characteristics are covariances because there is no residual return predictability from characteristics above ...

On Characteristic Decomposition and Quasi-characteristic Decomposition

2019
In this paper, the concepts of quasi-characteristic pair and quasi-characteristic decomposition are introduced. The former is a pair \((\mathcal {G}, \mathcal {C})\) of a reduced lexicographic Grobner basis \(\mathcal {G}\) and the W-characteristic set \(\mathcal {C}\) which is regular and extracted from \(\mathcal {G}\); the latter is the ...

The Characteristics of Tritanopia

Journal of the Optical Society of America, 1952
The paper describes how contact was made with a number of tritanopes through an article published in Picture Post, an illustrated weekly English journal.
