While much used in practice, latent variable models raise challenging estimation problems due to the intractability of their likelihood. Monte Carlo maximum likelihood (MCML), as proposed by Geyer & Thompson (1992 ), is a simulation-based approach to maximum likelihood approximation applicable to general latent variable models. MCML can be described as an importance sampling method in which the likelihood ratio is approximated by Monte Carlo averages of importance ratios simulated from the complete data model corresponding to an arbitrary value of the unknown parameter. This paper studies the asymptotic (in the number of observations) performance of the MCML method in the case of latent variable models with independent observations. This is in contrast with previous works on the same topic which only considered conditional convergence to the maximum likelihood estimator, for a fixed set of observations. A first important result is that when is fixed, the MCML method can only be consistent if the number of simulations grows exponentially fast with the number of observations. If on the other hand, is obtained from a consistent sequence of estimates of the unknown parameter, then the requirements on the number of simulations are shown to be much weaker. 相似文献

Gallup macropartisanship varies more over time than aggregatemeasures of partisanship employing the standard Michigan SurveyResearch Center (SRC) party identification measure, but previousanalyses do not provide direct evidence about why Gallup macropartisanshipis more variable. Although these differences could result fromthe short-term focus of the Gallup party affiliation question,aggregate-level analyses cannot test the effects of questionwording directly. Between March and October 1992, we conducteda series of question-wording experiments, employing six statewidecomputer-assisted telephone interview (CATI) surveys of Michiganadults, including a four-wave panel study. Our analyses stronglysuggest that the Gallup measure responds more to short-termpolitical conditions and clearly demonstrate that the Gallupmeasure is less stable over time. These individual-level resultshelp explain why Gallup macropartisanship varies more over timethan aggregate measures of partisanship employing the standardSRC measure and raise questions about the degree to which onecan generalize from analyses using the Gallup data to the researchliterature on party identification. 相似文献

In this article, I consider the position of gender and race in the tourism global production network in Kenya. To address a gap in scholarship on global production networks, I explore the racial and gender characteristics evident in functionally upgraded national tour operators and socially upgraded workers and community members around the Maasai Mara National Reserve. The main findings address the relation of race and gender to disarticulation practices identified in ‘societal’, ‘network’ and ‘territorial’ forms of embeddedness supported by racial and gender representations of skill capabilities and tourist desires. These practices and representations support a production network symbolized by whites, Kenyan‐Asians and expatriates in the highest value segments and jobs, and indigenous African, Maasai and female workers in the lowest value positions. The findings highlight how disarticulation in economic and social upgrading is a gendered and racial process that perpetuates social difference and hierarchy. 相似文献

We empirically explore the relevance and efficiency of risk‐taking behavior in tournaments. We use data from the National Basketball Association (NBA) and measure risk‐taking by the fraction of three‐point shots in basketball games. We examine how point differences between teams during games affect their subsequent risk‐taking behavior. It is found that teams that are trailing are more likely to increase their use of three‐point shots. We additionally analyze the consequences of this change in behavior. Enhanced risk‐taking is inefficient in the vast majority of cases and is only beneficial if a team is trailing by a rather large margin. We discuss possible explanations for these decision errors.

L'état du mariage diminuent le risque q'uon se suicide; spécialment c 'est vrai avec les hommes. Nous proposons que la rôle particuliere des femmes en maintenant la sociabilité et les obligations avec les parents explique cet fait. Cette explication s' accorde avec les théories de la parenté et du suicide.
La proportion du suicide q'uest enregistrée dans toute la Canada pendant les années 1951,1956,1961,1966, et 1971 révélent cet effet être la même chose durant tous les années. Les comparisons préliminaire entre des Canadiens anglais et français et entre des societées matrilinéal et patrilinéal s' accordent aussi avec les théories que nous présen-tons ici.
Marriage lowers the risk of suicide for men more than it does for women. It is proposed that the particular role of women in maintaining both normative and interactive integration of kinship systems on behalf of men best accounts for this particular finding. Such an explanation is compatible with existing theories of both kinship and suicide.
Rates of reported suicide for all Canada for the years 1951,1956,1961,1966, and 1971 were used to show that the extra protection of men is consistent through time, and the theoretical explanation offered was shown to receive support from a preliminary comparison of suicide rates in English and French Canada, in which kinship structure differs, as well as from suicide rates in matrilineal and patrilineal societies. 相似文献

With an identical data base—the SRCICPS election studiesconducted over the 1952–1976 period—scholars arriveat conflicting conclusions about the future politics of theSouth. One problem is alternative regional definitions—thesurvey category Solid South (which includes the states of theformer Confederacy minus Tennessee) or the combined categoriesSolid South and Border South. Another problem is the choiceto analyze native whites, whites, or all election participants.Based on data presented here, these choices are not neutral;rather, they influence the research findings. If the intentis to build upon the aggregate data-based research of Key andothers, one should use the Solid South definition. Moreover,if the intent is to predict about the future politics of theSouth, one should analyze all election participants. 相似文献

SUMMARY A method for comparing groupings of DNA sequences is presented, which utilizes randomization test methods to assign significance levels to a test statistic defined in terms of the Hamming distance between two sequences. The method, which is intuitively motivated by the analysis of variance procedure, partitions the variation caused by differences between clusters from the variation attributable to differences at random base pair locations within clusers. Implementation issues are discussed, and an example of the application of the method is provided. 相似文献

The article provides evidence that there is a relationship between government debt and interest rates via the demand for money. This relationship is examined through the wealth effect of government debt on money demand, and the robustness of the results is tested by the use of extreme bound analysis in addition to standard econometric techniques. We find that OLS regression shows government debt fnfecting the demand for money positively, implying that Federal government debt is net wealth. In addition, the extreme bound analysis shows that the estimates of the government debt coefficient are robust under alternative specifications of the Goldfeld model. 相似文献
