The Weak Instrument Problem of the System GMM Estimator in Dynamic Panel Data Models
Bun, Maurice J. G.; Windmeijer, Frank - 2009
The system GMM estimator for dynamic panel data models combines moment conditions for the model in first differences … model in terms of bias and root mean squared error. However, we show in this paper that in the covariance stationary panel … results are shown to extend to the panel data GMM estimators …

Identifying All Distinct Sample P-P Plots, with an Application to the Exact Finite Sample Distribution of the L1-FCvM Test Statistic
Hinloopen, Jeroen; Wagenvoort, Rien - 2010
P-p plots contain all the information that is needed for scale-invariant comparisons. Indeed, Empirical Distribution Function (EDF) tests translate sample p-p plots into a single number. In this paper we characterize the set of all distinct p-p plots for two balanced sample of size n absent...

How to implement the Bootstrap in Static or Stable Dynamic Regression Models
van Giersbergen, Noud P.A.; Kiviet, Jan F. - 2001
By combining two alternative formulations of a test statistic with two alternative resamplingschemes we obtain four different bootstrap tests. In the context of static linear regression modelstwo of these are shown to have serious size and power problems, whereas the remaining two areadequate...

Detecting Serial Dependence in Tail Events
Diks, Cees - 2002
A test for serial independence is proposed which is related to the BDS test but focuses on tail event probabilities rather than probabilities near the center of the distribution. The motivation behind this approach is to obtain a test more suitable for detecting structure in the tails, such as...

Correcting for Primary Study Misspecifications in Meta-Analysis
Koetse, Mark J.; Florax, Raymond J.G.M.; de Groot, … - 2005
In non-experimental sciences the errors associated with model misspecifications in primarystudies carry over to meta-analysis. We use Monte Carlo simulations to analyse the effects ofthese misspecifications on results of a meta-analysis using a meta-estimator that calculates asimple average...

Some Exact Tests for Manifest Properties of Latent Trait Models
de Gooijer, Jan G.; Yuan, Ao - 2010
Item response theory is one of the modern test theories with applications in educational and psychological testing. Recent developments made it possible to characterize some desired properties in terms of a collection of manifest ones, so that hypothesis tests on these traits can, in principle,...

The Impact of Effect Size Heterogeneity on Meta-Analysis: A Monte Carlo Experiment
Koetse, Mark J.; Florax, Raymond J.G.M.; de Groot, … - 2007
In this paper we use Monte Carlo simulation to investigate the impact of effect size heterogeneity on the results of a meta-analysis. Specifically, we address the small sample behaviour of the OLS, the fixed effects regression and the mixed effects meta-estimators under three alternative...

A K-Sample Homogeneity Test Based on the Quantification of the p-p Plot : The Harmonic Weighted Mass Index
Hinloopen, Jeroen; Wagenvoort, Rien; Marrewijk, Charles van - 2008
We propose a quantification of the p-p plot that assigns equal weight to all distances between the respective distributions: the surface between the p-p plot and the diagonal. This surface is labelled the Harmonic Weighted Mass (HWM) index. We introduce the diagonal-deviation (d-d) plot that...

Two Independent Pivotal Statistics that test Location and Misspecification and add up to the Anderson-Rubin Statistic
Kleibergen, Frank - 2002
We show that the Anderson-Rubin (AR) statistic is the sum of two independent piv-otal statistics. One statistic is a score statistic that tests location and the other statistictests misspecification. The chi-squared distribution of the location statistic has a degreesof freedom parameter that is...
