Distributions You Can Count On …But What’s the Point?

Econometrics, 2020
The Poisson regression model remains an important tool in the econometric analysis of count data. In a pioneering contribution to the econometric analysis of such models, Lung-Fei Lee presented a specification test for a Poisson model against a broad ...

Specification tests for the propensity score [PDF]

Journal of Econometrics, 2019
This paper proposes new nonparametric diagnostic tools to assess the asymptotic validity of different treatment effects estimators that rely on the correct specification of the propensity score. We derive a particular restriction relating the propensity score distribution of treated and control groups, and develop specification tests based upon it. The

Inference for the Parameters of a Zero-Inflated Poisson Predictive Model

Risks
In the insurance sector, Zero-Inflated models are commonly used due to the unique nature of insurance data, which often contain both genuine zeros (meaning no claims made) and potential claims.

A New Technique for Finding Needles in Haystacks: A Geometric Approach to Distinguishing Between a New Source and Random Fluctuations

, 2005
We propose a new test statistic based on a score process for determining the statistical significance of a putative signal that may be a small perturbation to a noisy experimental background.

Use of the score test as a goodness-of-fit measure of the covariance structure in genetic analysis of longitudinal data

Genetics Selection Evolution, 2003
Model selection is an essential issue in longitudinal data analysis since many different models have been proposed to fit the covariance structure. The likelihood criterion is commonly used and allows to compare the fit of alternative models.

Scoring the Stroop test

Acta Psychologica, 1965
The Stroop Test, also known as the color-word naming test, has been used in over sixty published psychological studies since the test was originally described by Stroop (2). The test has been used to attempt to measure a variety of processes and traits in the cognitive and personality domains, which it is not the purpose of this article to review.

Decomposing international gender test score differences

Journal for Labour Market Research, 2018
In this paper, we decompose worldwide PISA mathematics and reading scores. While mathematics scores are still tilted towards boys, girls have a larger advantage in reading over boys.
