Models to investigate categorical data can be divided into preprocessing, limited parameterization, and formal logit models. To illustrate the advantages of preprocessing and limited parameterization models they are applied to a data set of tenure and type of housing choice before the data are examined with hierarchical logit and nested logit models. The preprocessing approaches are useful in selecting optimal subsets of independent variables with respect to the dependent variable. The ease of application and interpretation of a limited parameterization approach extends the clarity of the results from the preprocessing approaches. Because some variables are only relevant at specific levels of other independent variables, nonstandard (nested) logit models are necessary to understand the nested relationships.  相似文献

ABSTRACT This paper explores theories of population growth, and implied economic growth, among the major U.S. metro areas and regions. One set of theoretical arguments favor the growth of large cities, while an alternative set of arguments favor the growth of the smaller urban areas. Still another set of arguments combine economic space and urban size in the concept of regional growth centers as the engines of regional growth. Granger causality tests are applied to determine the role of urban size or growth centres as engines of regional growth. The test results indicate no causal relationship exists.  相似文献

The combined application of fission track analysis and neutron activation-induced β-autoradiography to map the trace element distributions of scandium, cobalt, uranium and rare earth elements in fossil bone samples from East Africa is described. Both uranium and the rare earth elements are incorporated into bone apatite during fossilisation, whereas scandium and cobalt occur additionally in any iron-manganese minerals precipitated in pore spaces within the bone cortex. The distribution of uranium is different from that of the rare earth elements in the fossil bone cortices; it enters fossil bone more rapidly and is sensitive to changes in the redox potential of the palaeogroundwater.  相似文献
