    Survey data and Bayesian analysis: a cost-efficient way to estimate customer equity

    We present a Bayesian framework for estimating the customer lifetime value (CLV) and the customer equity (CE) based on the purchasing behavior deducible from the market surveys on customer purchasing behavior....

    An analytic and systematic framework for estimating metabolic flux ratios from 13C tracer experiments

    Metabolic fluxes provide invaluable insight on the integrated response of a cell to environmental stimuli or genetic modifications. Current computational methods for estimating the metabolic fluxes from 13C isoto...

    Equivalence of Metabolite Fragments and Flow Analysis of Isotopomer Distributions for Flux Estimation

    The most accurate estimates of the activity of metabolic pathways are obtained by conducting isotopomer tracer experiments. The success of this method, however, is intimately dependent on the quality and amoun...

    Finding Feasible Pathways in Metabolic Networks

    Recent small-world studies of the global structure of metabolic networks have been based on the shortest-path distance. In this paper, we propose new distance measures that are based on the structure of feasib...
