The R Package geepack for Generalized Estimating Equations [PDF]

This paper describes the core features of the R package geepack, which implements the generalized estimating equations (GEE) approach for fitting marginal generalized linear models to clustered data.

A generalized FKKM theorem and variational inequality [PDF]

We present a generalized FKKM Theorem and it's application to the existence of solution for the variationals inequalities using a generalized coercivity type condition for correspondences defined in L-space.L-structure, L-spaces, L-KKM correspondences, L-

Generalized Methods of Trimmed Moments [PDF]

High breakdown-point regression estimators protect against large errors and data contamination. We adapt and generalize the concept of trimming used by many of these robust estimators so that it can be employed in the context of the generalized method of

Moments of the generalized hyperbolic distribution [PDF]

In this paper we demonstrate a recursive method for obtaining the moments of the generalized hyperbolic distribution. The method is readily programmable for numerical evaluation of moments.

EQUATIONAL THEORIES GENERATED BY HYPERSUBSTITUTIONS OF TYPE (n)

International Journal of Algebra and Computation, 2002
Hypersubstitutions map n-ary operation symbols to n-ary terms. Such mappings can be uniquely extended to mappings defined on the set of all terms. It turns out that the kernels of hypersubstitutions are fully invariant congruence relations on the (absolutely free) term algebra of the considered type. For an arbitrary type τ = (n), n ≥ 1, i.e.

All idempotent and regular elements in the monoid of generalized hypersubstitutions for algebraic systems of type (2; 2)

Asian-European Journal of Mathematics, 2019
There are two different concepts for hypersubstitutions for algebraic systems [K. Denecke and D. Phusanga, Hyperformulas and solid algebraic systems, Studia Logica 90(2) (2008) 263–286; J. Koppitz and D. Phusanga, The monoid of hypersubstitutions for algebraic systems, J. Announcements Union Sci. Sliven 33(1) (2018) 120–127].

The semantical kernel of a generalized hypersubstitution

2003
Created seemingly for its own sake by the authors [``Generalized hypersubstitutions and strongly solid varieties'', Proceedings of the 59th workshop on general algebra, Potsdam, Germany, 2000 (2000)], the notion of generalized hypersubstitution is considered with regard to associated Galois connections and possible (albeit dubitable) interpretations in

Tree transformations defined by generalized hypersubstitutions

2003
Let \(W_\tau(X)\) be the set of all \(\tau\)-terms with variables in \(X\), where \(\tau\) is a type of algebras and \(X\) is a countably infinite set of variables. A generalized hypersubstitution assigns a term \(\sigma(f)\in W_\tau(X)\) to each function symbol \(f\) in \(\tau\), and is then extended in a natural way to a mapping \(\widehat\sigma: W_ ...
