Autoregressive aided periodogram bootstrap for time series

Kreiss, Jens-Peter; Paparoditis, Efstathios - 2001

A bootstrap methodology for the periodogram of a stationary process is proposed which is based on a combination of a … time domain parametric and a frequency domain nonparametric bootstrap. The parametric fit is used to generate periodogram … theory developed shows validity of the proposed bootstrap procedure for a large class of periodogram statistics. For …

The efficiency of bias-corrected estimators for nonparametric kernel estimation based on local estimating equations

Kauermann, Göran; Müller, Marlene; Carroll, Raymond J. - 1997

Stuetzle and Mittal (1979) for ordinary nonparametric kernel regression and Kauermann and Tutz (1996) for nonparametric generalized linear model kernel regression constructed estimators with lower order bias than the usual estimators, without the need for devices such as second derivative...

Nonparametric kernel and regression spline estimation in the presence of measurement error

Maca, J. D.; Carroll, Raymond J.; Ruppert, David - 1997

In many regression applications both the independent and dependent variables are measured with error. When this happens, conventional parametric and nonparametric regression techniques are no longer valid. We consider two different nonparametric techniques, regression splines and kernel...

On robustness of model-based bootstrap schemes in nonparametric time series analysis

Neumann, Michael H. - 1997

asymptotically for the bootstrap to be valid. However, certain model-based bootstrap methods remain valid for some interesting … bootstrap schemes remain valid for supremum-type functionals as long as they mimic the corresponding finite-dimensional joint … distributions consistently. As an example, we investigate a finite order Markov chain bootstrap in the context of a general …

Polynomial regression and estimation function in the presence of multiplication measurement error, with application to nutrition

Iturria, Stephen J.; Carroll, Raymond J.; Firth, David - 1997

In this paper we consider the polynomial regression model in the presence of multiplicative measurement error in the predictor. Consistent parameter estimates and their associated standard errors are derived. Two general methods are considered, with the methods differing in their assumptions...

Microfinance Institutions’ Efficiency in the MENA region: a Bootstrap-DEA approach

Ben Abdelkader, Ines; Hathroubi, Salem; Ben Jemaa, … - 2012

The purpose of this study is to evaluate the performance of microfinance institutions in The MENA region over the period 2006-2009. Following Simar and Wilson (1998, 2000) we use a DEA-Bootstrapping methodology to drift appropriate measures of DEA efficiency scores. The estimated results show...

Testing for monotonicity in expected asset returns

Romano, Joseph P.; Wolf, Michael - 2013

Many postulated relations in finance imply that expected asset returns strictly increase in an underlying characteristic. To examine the validity of such a claim, one needs to take the entire range of the characteristic into account, as is done in the recent proposal of Patton and Timmermann...

Alterntive tests for monotonicity in expected asset returns

Romano, Joseph P.; Wolf, Michael - 2011

Many postulated relations in finance imply that expected asset returns should monotonically increase in a certain characteristic. To examine the validity of such a claim, one typically considers a finite number of return categories, ordered according to the underlying characteristic. A standard...

Is momentum due to data-snooping?

Ericsson, Johan; González, Andrés - 2003

This paper explores the profitability of portfolio-based momentum strategies. The data consists of all NYSE, AMEX, and NASDAQ stocks on the CRSP database. The analysis considers the period July 1963 to December 2002 and the tests are performed on portfolios formed on industry, size and...

Errors in survey based quality evaluation variables in efficiency models of primary care physicians

Kittelsen, Sverre A. C.; Galtung Kjæserud, Guri; … - 2001

Efficiency analyses in the health care sector are often criticised for not incorporating quality variables. The definition of quality of primary health care has many aspects, and it is inevitably also a question of the patients’ perception of the services received. This paper uses variables...
