(Skew) Filters in Residuated Skew Lattic [PDF]

open access: yesScientific Annals of Computer Science, 2018
In this paper, we show the relationship between (skew) deductive system and (skew) filter in residuated skew lattices. It is shown that if a residuated skew lattice is conormal, then any skew deductive system is a skew filter under a condition and deductive system and skew deductive system are equivalent under some conditions too.

On mixtures of skew normal and skew $$t$$ -distributions [PDF]

open access: yesAdvances in Data Analysis and Classification, 2013
Finite mixture of skew distributions have emerged as an effective tool in modelling heterogeneous data with asymmetric features. With various proposals appearing rapidly in the recent years, which are similar but not identical, the connections between them and their relative performance becomes rather unclear.

SKEWNESS AND PERMUTATION [PDF]

open access: yesCladistics, 1992
Abstract— The skewness criterion of phylogenetic structure in data is too sensitive to character state frequencies, is not sensitive enough to number of characters (degree of corroboration) and relies on counts of arbitrarily‐resolved bifurcating trees. For these reasons it can give misleading results.

Normal but Skewed?

open access: yes, 2021
We propose a multivariate normality test against skew normal distributions using higher-order loglikelihood derivatives which is asymptotically equivalent to the likelihood ratio but only requires estimation under the null. Numerically, it is the supremum of the univariate skewness coefficient test over all linear combinations of the variables.

Skew throttling

open access: yesAustralas. J Comb., 2019
Zero forcing is a process that colors the vertices of a graph blue by starting with some vertices blue and applying a color change rule. Throttling minimizes the sum of the number of initial blue vertices and the time to color the graph. In this paper, we study throttling for skew zero forcing.

Constructions of skew-tolerant and skew-detecting codes [PDF]

open access: yesIEEE Transactions on Information Theory, 1993
Summary: Recently the paradigm of skew-tolerant parallel asynchronous communication was introduced, along with constructions for codes that can tolerate or detect skew. Some of these constructions were improved by the third author [Construction of \((t_ 1, t_ 2)\)-tolerant codes, Proc. Dilijan Conf; Sept. 1991].

Skew Randić Matrix and Skew Randić Energy

open access: yesTransactions on Combinatorics, 2014
Let $G$ be a simple graph with an orientation $σ$, which assigns to each edge a direction so that $G^σ$ becomes a directed graph. $G$ is said to be the underlying graph of the directed graph $G^σ$. In this paper, we define a weighted skew adjacency matrix with Randć weight, the skew Randić matrix ${\bf R_S}(G^σ)$, of $G^σ$ as the real skew symmetric ...

On skew-symmetric games

open access: yesJournal of the Franklin Institute, 2018
By resorting to the vector space structure of finite games, skew-symmetric games (SSGs) are proposed and investigated as a natural subspace of finite games. First of all, for two player games, it is shown that the skew-symmetric games form an orthogonal complement of the symmetric games.
