A Practical View on Renaming
We revisit variable renaming from a practitioner's point of view, presenting
concepts we found useful in dealing with operational semantics of pure Prolog.
A concept of relaxed core representation is introduced, upon which a concept of
prenaming is built. Prenaming formalizes the intuitive practice of renaming
terms by just considering the necessary bindings, where now some passive
"bindings" x/x may be necessary as well. As an application, a constructive
version of variant lemma for implemented Horn clause logic has been obtained.
There, prenamings made it possible to incrementally handle new (local)
variables.Comment: In Proceedings WLP'15/'16/WFLP'16, arXiv:1701.0014
Generic Traces and Constraints, GenTra4CP revisited
The generic trace format GenTra4CP has been defined in 2004 with the goal of
becoming a standard trace format for the observation of constraint solvers over
finite domains. It has not been used since. This paper defines the concept of
generic trace formally, based on simple transformations of traces. It then
analyzes, and occasionally corrects, shortcomings of the proposed initial
format and shows the interest that a generic tracer may bring to develop
portable applications or to standardization efforts, in particular in the field
of constraints
A note on testing the covariance matrix for large dimension
We consider the problem of testing hypotheses regarding the covariance matrix of multivariate normal data, if the sample size s and dimension n satisfy lim [n,s→∞] n/s = y. Recently, several tests have been proposed in the case, where the sample size and dimension are of the same order, that is y ∈ (0,∞). In this paper we consider the cases y = 0 and y = ∞. It is demonstrated that standard techniques are not applicable to deal with these cases. A new technique is introduced, which is of its own interest, and is used to derive the asymptotic distribution of the test statistics in the extreme cases y = 0 and y = ∞. --sphericity test,random matrices,Wishart distribution
