Computing Sum of Products about the Mean with Pairwise Algorithms
1997
We discuss pairwise algorithms, a kind of computational algorithm which can be useful in dynamically updating statistics as new samples of data are collected. Since test data are usually collected through time as individual data sets, these algorithms would be profitably used in computer programs to treat this situation. Pair-wise algorithms are presented for calculating the sum of products of deviations about the mean for adding a sample of data (or removing one) to the whole data set.
Comparing normal means: new methods for an old problem
2007
Comparing the means of two normal populations is an old problem in mathematical statistics, but there is still no consensus about its most appropriate solution. In this paper we treat the problem of comparing two normal means as a Bayesian decision problem with only two alternatives: either to accept the hypothesis that the two means are equal, or to conclude that the observed data are, under the assumed model, incompatible with that hypothesis. The combined use of an information-theory based loss function, the intrinsic discrepancy (Bernardo and Rueda 2002}, and an objective prior function, the reference prior \citep{Bernardo 1979; Berger and Bernardo 1992), produces a new solution to this…
Los derechos fundamentales como normas jurídicas materiales en la teoría de Robert Alexy
2011
RESUMEN. La teoría de los derechos fundamentales de Robert Alexy se fundamenta en un concepto material de norma jurídica que es de carácter doble. Por un lado, se define por los rasgos propios de los principios, en consonancia con la idea de argumentación correcta. Pero, por otro lado, sigue teniendo peso la validez jurídica de las normas que contienen derechos fundamentales, consideradas como reglas constitucionales. Tal y como se argumenta en el trabajo, esta ambigüedad de la teoría de la norma de Alexy permite distintos acercamientos, positivistas y no positivistas, que es signo de su riqueza teórica. ABSTRACT. The theory of the civil rights of Robert Alexy is based on a material concept…
Formal Variation and Language Change in Catalan Quantifiers : the Role of Pragmatics
2020
This article studies the formal variation of the masculine singular forms of the quantifiers u/un 'one', algú/algun 'someone, some', ningú/ningun 'no-one, anyone, not one, any, none' and cada u/cada un 'everyone, each one' in contemporary Catalan. The standard uses of these forms are contrasted with dialectal uses, obtained from a thorough search in oral and written corpora. In addition, they are compared with the uses in the other Romance languages and with their historical evolution in Catalan. The whole set of data, and especially the dialectal information on the Valencian area, allow us to explain the various factors that have interacted in the variation and formal change of these quant…
Rivoluzione cognitivista e teoria del diritto: un programma di ricerca
2017
Questo scritto ha un carattere esclusivamente programmatico. È dedicato alla presentazione delle linee essenziali di un programma di ricerca nel quale siamo impegnati già da un po’ di tempo, e che intendiamo sviluppare nel prossimo futuro. Nei primi due paragrafi tratteggiamo sommariamente il contesto culturale e scientifico della “rivoluzione cognitivista”, nel quale il nostro programma si colloca (behavioural law and economics; responsabilità e imputabilità; euristiche e bias nella decisione giudiziale). Nel terzo paragrafo elenchiamo le linee di ricerca affini già battute da altri autori. Il quarto paragrafo è dedicato alla formulazione del nucleo centrale del nostro programma: quali son…

Regular Minimality and Thurstonian-type modeling
2009
Abstract A Thurstonian-type model for pairwise comparisons is any model in which the response (e.g., “they are the same” or “they are different”) to two stimuli being compared depends, deterministically or probabilistically, on the realizations of two randomly varying representations (perceptual images) of these stimuli. The two perceptual images in such a model may be stochastically interdependent but each has to be selectively dependent on its stimulus. It has been previously shown that all possible discrimination probability functions for same–different comparisons can be generated by Thurstonian-type models of the simplest variety, with independent percepts and deterministic decision ru…
McKay natural correspondences on characters
2014
Let [math] be a finite group, let [math] be an odd prime, and let [math] . If [math] , then there is a canonical correspondence between the irreducible complex characters of [math] of degree not divisible by [math] belonging to the principal block of [math] and the linear characters of [math] . As a consequence, we give a characterization of finite groups that possess a self-normalizing Sylow [math] -subgroup or a [math] -decomposable Sylow normalizer.
Intersection subgroups of complex hyperplane arrangements
2000
Abstract Let A be a central arrangement of hyperplanes in C n , let M( A ) be the complement of A , and let L ( A ) be the intersection lattice of A . For X in L ( A ) we set A X ={H∈ A : H⫆X} , and A /X={H/X: H∈ A X } , and A X ={H∩X: H∈ A \ A X } . We exhibit natural embeddings of M( A X ) in M( A ) that give rise to monomorphisms from π 1 (M( A X )) to π 1 (M( A )) . We call the images of these monomorphisms intersection subgroups of type X and prove that they form a conjugacy class of subgroups of π 1 (M( A )) . Recall that X in L ( A ) is modular if X+Y is an element of L ( A ) for all Y in L ( A ) . We call X in L ( A ) supersolvable if there exists a chain 0⫅X 1 ⫅⋯⫅X d =X in L ( A ) …
Large subgroups of a finite group of even order
2011
It is shown that if G G is a group of even order with trivial center such that | G | > 2 | C G ( t ) | 3 |G|>2|C_{G}(t)|^{3} for some involution t ∈ G t\in G , then there exists a proper subgroup H H of G G such that | G | > | H | 2 |G|> |H|^{2} . If | G | > | C G ( t ) | 3 |G|>|C_{G}(t)|^{3} and k ( G ) k(G) is the class number of G G , then | G | ≤ k ( G ) 3 |G|\leq k(G)^{3} .
