This paper analyzes the properties of a class of estimators, tests, and confidence sets (CSs) when the parameters are not identified in parts of the parameter space. Specifically, we consider estimator criterion functions that are sample averages and are smooth functions of a parameter θ . This includes log likelihood, quasi-log likelihood, and least squares criterion functions. We determine th...

Section A gives empirical results for the Angrist and Krueger (1991) data and discusses implementation of PI tests and confidence sets. Section B provides further details on the derivation of the limit problems discussed in Section 2 of the paper. Section C shows that general nonlinear GMM models which are weakly identified in the sense of Stock and Wright (2000) give rise to limiting problems ...

This article examines the null limit distribution of quasi-likelihood ratio (QLR) statistic for testing linearity condition against smooth transition autoregressive (STAR) model. We explicitly show that QLR test weakly converges to a functional multivariate Gaussian process under linearity, which is done by resolving issue identification problem arises in two different ways null. In contrast wi...

Born in Bradford (BiB) has followed the lives of 13,776 children born district between 2007 and 2011. Children birth cohort are now entering adolescence, next phase research - Age Wonder (AoW) will be a whole city capturing experiences 30,000 adolescents progressing into young adulthood. This protocol focuses on one component AoW programme: qualitative longitudinal (QLR). The study gathe...

This article reflects on the contribution of qualitative longitudinal research (QLR) to understandings homeless peoples’ experiences support service interventions in an era austerity UK. It brings into ‘analytic conversation’ data from evaluations projects operated by voluntary sector organisations Scotland. With fieldwork spanning 2014-2019, analysis expands analytical potential pooling small-...

Due to the global warming and dynamic changes in pathogenic virulence, leaf rust caused by Puccinia triticina has greatly expanded its epidermic region become a severe threat wheat production. Genetic bases of resistance mainly rely on (Lr) gene or quantitative trait locus (QLr). Although these genetic loci have been insensitively studied during last two decades, an updated overview Lr/QLr geno...

There has been an increasing focus in the UK on support provided to Armed Forces community, with publication of Covenant (2011), Strategy for our Veterans (2018) and first ever Office Veterans’ Affairs (2019). is also important body research – including longitudinal focusing transitions from military civilian life, much which quantitative. At same time, witnessed a period unprecedented welfare ...

We propose a model of quantum-like (QL) processing of mental information. This model is based on quantum information theory. However, in contrast to models of "quantum physical brain" reducing mental activity (at least at the highest level) to quantum physical phenomena in the brain, our model matches well with the basic neuronal paradigm of the cognitive science. QL information processing is b...

We study the typical domain size and configuration character of a randomly perturbed system exhibiting continuous symmetry breaking. As a model system we use rod-like objects within a cubic lattice interacting via a Lebwohl–Lasher-type interaction. We describe their local direction with a headless unit director field. An example of such systems represents nematic LC or nanotubes. We further int...
