Consistency of nonlinear regression quantiles under Type I censoring weak dependence and general covariate design
Oberhofer, Walter; Haupt, Harry - Wirtschaftswissenschaftliche Fakultät, Universität … - 2005
For both deterministic or stochastic regressors, as well as parametric nonlinear or linear regression functions, we prove the weak consistency of the coefficient estimators for the Type I censored quantile regression model under different censoring mechanisms with censoring points depending on...

Nile perch demand in the Netherlands: are exports from Kenya, Tanzania and Uganda source-differentiated?
Muhammad, Andrew - In: Agrekon 48 (2009) 2
This study examined Nile perch demand in the Netherlands and assessed the importance of country of origin as a … determining factor. Import demand equations were estimated using the absolute price version of the Rotterdam model where Nile …). The Armington framework (source-differentiation) is often used when estimating import demand for a similar product from …

Nonlinear Regression with Harris Recurrent Markov Chains
Li, Degui; Tjøstheim, Dag; Gao, Jiti - Department of Econometrics and Business Statistics, … - 2012
In this paper, we study parametric nonlinear regression under the Harris recurrent Markov chain framework. We first consider the nonlinear least squares estimators of the parameters in the homoskedastic case, and establish asymptotic theory for the proposed estimators. Our results show that the...

On the accuracy of statistical procedures in Microsoft Excel 2010
Mélard, Guy - In: Computational Statistics 29 (2014) 5, pp. 1095-1128
All previous versions of Microsoft Excel until Excel 2007 have been criticized by statisticians for several reasons, including the accuracy of statistical functions, the properties of the random number generator, the quality of statistical add-ins, the weakness of the Solver for nonlinear...

Nonparametric estimation via local estimating equations, with applications to nutrition calibration
Carroll, Raymond J.; Ruppert, David; Welsh, A. H. - Sonderforschungsbereich 373, Quantifikation und … - 1997
Estimating equations have found wide popularity recently in parametric problems, yielding consistent estimators with asymptotically valid inferences obtained via the sandwich formula. Motivated by a problem in nutritional epidemiology, we use estimating equations to derive nonparametric...

A model specification test
Bartels, Knut - Sonderforschungsbereich 373, Quantifikation und … - 1998
A general model specification test of a parametric model against a nonparametric or semiparametric alternative is studied. The test statistic employs a fixed kernel, not varying by a bandwidth. This test is proved to be consistent, the asymptotic distribution is derived and shown to be...
