A new regression-based approach is proposed for modeling marketing the analysis, the functional form of the effect of each independent variable, and the appropriate transformation for the dedatabases. The approach is Bayesian and provides a number of significant pendent variable. improvements over current methods. Independent variables can enter into This article introduces a highly flexible Ba...

When there are several replicates available at each level combination of two factors, testing non-additivity can be done by the usual two-way ANOVA method. However, the ANOVA method cannot be used when the experiment is unreplicated (one observation per cell of the two-way classification). Several tests have been developed to address non-additivity in unreplicated experiments starting with Tuke...

Using an increasing returns specification for distribution, an inverted-U pattern between the share of distribution in GDP and the level of development is shown to arise. A cross-section time series data set is constructed and merged with one used to analyze the service sector. In contrast to the rising pattern found for services, an average time series relation that exhibits an inverted-U patt...

This paper presents two score tests to determine a value for the Box–Cox transformation parameter. The test based on expected information performs better in small samples and is computationally simpler than the one based on observed information; therefore, the former is recommended.  2002 Elsevier Science B.V.

One of the major issues in the analysis of unemployment durations concerns the distinction between duration dependence of the exit rate out of unemployment and unobserved heterogeneity. Empirical studies rely heavily on functional form restrictions, which may be hazardous. We present a method for the nonparametric estimation of both phenomena. This method is designed to be applicable to aggrega...

In this paper we study the description of saturation in Balitsky, Jalilian-Marian, Iancu, McLerran, Weigert, Leonidov and Kovner (BJIMWLK) picture when restricted to observables made up only from dipole operators. We derive a functional form of the evolution equation for the dipole probability distribution and find a one-parameter family of exact solutions to the dipole evolution equations.

We say a countable model A has a 0-basis if the types realized in A are uniformly computable. We say A has a (d-)decidable copy if there exists a model B ∼= A such that the elementary diagram of B is (d-)computable. Goncharov, Millar, and Peretyat’kin independently showed there exists a homogeneous model A with a 0-basis but no decidable copy. We extend this result here. Let d ≤ 0′ be any low2 ...

This paper uses the marginal treatment effect (MTE) to unify the nonparametric literature on treatment effects with the econometric literature on structural estimation using a nonparametric analog of a policy invariant parameter; to generate a variety of treatment effects from a common semiparametric functional form; to organize the literature on alternative estimators; and to explore what poli...

where p,q and r are arbitrary constants. We construct twenty five exact traveling wave solutions of the (1+1)-dimensional modified KdV equation involving parameter by applying this method. The solutions are presented in terms of the hyperbolic, the trigonometric and the rational functional form including solitons and periodic solutions. Moreover, it is worth mentioning that one of our obtained ...
