Effect size is a concept that can be especially useful in bioequivalence and studies designed to find important and not just statistically significant differences among responses to treatments based on independent random samples. We develop and explore a new effect size related to a maximal...

This paper proposes a conceptual and methodological understanding of the nature and extent of NGO integration into state and donor systems that is based on a dynamic view of NGOs as multidimensional organisations with financial, political, interpersonal, legal, values a technical dimensions that...

The usefulness of logistic regression depends to a great extent on the correct specification of the relation between a binary response and characteristics of the unit on which the response is recoded. Currently used methods for testing for misspecification (lack of fit) of a proposed logistic...

Linear programming-based estimation procedures are used in a variety of arenas. Two notable areas are multiattribute utility models (LINMAP) and production frontiers (data envelopment analysis (DEA)). Both LINMAP and DEA have theoretical and managerial advantages. For example, LINMAP treats...

The positioning and pricing of a new brand requires knowledge about the relationship of both demand and cost with potential attribute locations and prices. This paper addresses this problem and illustrates it in the context of the automobile market. Multi-attribute expected utility theory which...

The efficient operation of a salesforce is a critical element in the profitability of many firms. Three factors play key roles: the salesforce's size, its allocation and its productivity. This gives rise to the following questions: can salesforce performance be improved by (1) hiring more...

This paper extends the scanner-based choice literature by explicitly incorporating individual-level brand-preference data. We illustrate our model using a unique data set that combines survey and scanner data collected from the same individuals. The addition of individual-specific...

The classical derivation of a traffic stream model (e.g. speed/concentration relation) from the equilibrium solutions of the Prigogine-Herman kinetic equation invokes the nontrivial assumption that the underlying distribution of desired speeds is nonzero for vanishingly small speeds. In this...

Classical deterministic (or "mechanical") developments of traffic stream models from car-following models are criticized on the following basis. The evaluation of the constant of integration for initial conditions corresponding to speed zero and headway equal to the reciprocal of jam density...
