This paper examines the sampling properties of a number of serial correlation tests in dynamic linear models which include one or two lags of the dependent variable. Among the tests considered are the Durbin-Watson (DW) bounds test, modified versions of the DW proposed recently by King and Wu and Inder, Durbin's m test, Inder's point optimal test and a Hausman type test. Sampling designs include models with one or two lags of the dependent variable. The m, Hausman, and Inder's tests have the best performance, while Inder's modified DW test appears to be better than the other DW based tests. Results also suggest that tests are less powerful and more sensitive to design parameters in models with higher dynamics, with the DW-based tests being the most sensitive. 相似文献

This article introduces a feasible estimation method for a large class of semi and nonparametric models. We present the family
of generalized structured models which we wish to estimate. After highlighting the main idea of the theoretical smooth backfitting
estimators, we introduce a general estimation procedure. We consider modifications and practical issues, and discuss inference,
cross validation, and asymptotic theory applying the theoretical framework of Mammen and Nielsen (Biometrika 90: 551–566,
2003). An extensive simulation study shows excellent performance of our method. Furthermore, real data applications from environmetrics
and biometrics demonstrate its usefulness. 相似文献

Summary. The data that are analysed are from a monitoring survey which was carried out in 1994 in the forests of Baden-Württemberg, a federal state in the south-western region of Germany. The survey is part of a large monitoring scheme that has been carried out since the 1980s at different spatial and temporal resolutions to observe the increase in forest damage. One indicator for tree vitality is tree defoliation, which is mainly caused by intrinsic factors, age and stand conditions, but also by biotic (e.g. insects) and abiotic stresses (e.g. industrial emissions). In the survey, needle loss of pine-trees and many potential covariates are recorded at about 580 grid points of a 4 km × 4 km grid. The aim is to identify a set of predictors for needle loss and to investigate the relationships between the needle loss and the predictors. The response variable needle loss is recorded as a percentage in 5% steps estimated by eye using binoculars and categorized into healthy trees (10% or less), intermediate trees (10–25%) and damaged trees (25% or more). We use a Bayesian cumulative threshold model with non-linear functions of continuous variables and a random effect for spatial heterogeneity. For both the non-linear functions and the spatial random effect we use Bayesian versions of P -splines as priors. Our method is novel in that it deals with several non-standard data requirements: the ordinal response variable (the categorized version of needle loss), non-linear effects of covariates, spatial heterogeneity and prediction with missing covariates. The model is a special case of models with a geoadditive or more generally structured additive predictor. Inference can be based on Markov chain Monte Carlo techniques or mixed model technology. 相似文献

This paper is concerned with the minimal number of profiles at which a unanimous and anonymous social choice function for
three alternatives is manipulable. The lower bound is derived and examples of social choice functions attaining the lower
bound are given. It is conjectured that these social choice functions are in fact all minimally manipulable social choice
functions. Since some of these social choice functions are Pareto optimal, it follows that the lower bound also holds for
Pareto optimal and anonymous social choice functions. Some of the minimally manipulable Pareto optimal and anonymous social
choice functions can be interpreted as status quo voting. 相似文献

Leading PR-historiography provides a picture of an evolutionary process of public relations activity in which PR develops from a manipulative to a two-way, dialogue-oriented communication process. We analyzed a number of public relations textbooks to determine how their authors present PR history. Our major findings are: (1) The construct of the progressive development of PR is evenly spread throughout textbooks; (2) The majority of textbooks simply rely on storytelling and not on a theory-driven approach to PR history as we would prefer to see in PR textbooks that are used to teach university students; (3) The PR history presented in the books seems to be influenced by a paradigmatic stance. However, citation context analysis did not enable us to trace back the dissemination of this viewpoint to one paradigmatic author, and so we assume that the so-called obliteration effect prevents this proof. 相似文献

Self-responsible behavior is introduced as a new part of work performance. It is defined as an organizational behavior, which should be well adapted to a difficult and extra-ordinary situation lacking a well-defined task. A decreasing frequency of clearly defined tasks and roles is observable because of changes due to general restructuring, cutting off hierarchy levels and out-sourcing of major organizational functions. Employees acting in a self-responsible manner face these situations by defining their tasks on their own risk. Other new theories of extra-role behavior (e.g. organizational citizenship behavior, contextual performance or whistle blowing) are classified as either self-responsible or as “carrying out one′s duty” regarding the criteria ‘usefulness for the organization’ and ‘gratuitousness of acts’. 相似文献

The study describes collaborative involvement of child welfare agencies in Sweden with mandated reporters and analyses the association between socioeconomic and demographic factors as well as collaborative involvement on referral rates. The empirical material consists of data collected on location in 100 Swedish child welfare agencies, augmented with register data. The study shows that: (i) collaboration is common in the child welfare field, (ii) structural factors moderately predict municipal variations in child welfare referrals and (iii) most importantly, that collaboration on the aggregate level seems to serve as a marginal, or even counter-productive, measure in identifying children and adolescents at risk. The results are particularly discussed in the context of policy principles in Swedish child welfare, i.e. collaboration as a statutory requirement for child welfare agencies and the official notion of collaboration as an important means to facilitate early interventions. 相似文献
