  • Scientists, engineers and the like are a strange lot. Unperturbed by societal norms, they direct their energies to finding better alternatives to existing theories and concocting solutions to unsolved problems. Driven by an insatiable curiosity, they record their observations and crunch the numbers. This tome is about the science of crunching. It’s about digging out something of value from the detritus that others tend to leave behind. The described approaches involve constructing models to process the available data.

  • Our model identifies new explanations for why large and small firms make different insurance offer decisions; they are based on turnover rates and within-firm and between-firm heterogeneities. Large firms tend to have greater within-firm heterogeneity than small ones, and so they are more likely to have some employees who strongly desire health insurance and less likely to attract only workers who do not find health insurance attractive.

  • Next, we can modify our model to account for different firm sizes. For notational convenience and ease of exposition, we have used a continuum model. A firm hires a unit mass of consumers. The size of the firm then becomes a normalization and hence has no bearing on the dynamics and steady-state properties. In practice, firms hire a finite number of workers, and the law of large number becomes a poor approximation when the firm is small. Even when a small firm draws from the same work force as any other firm, the variance of workers’ health-care cost may be larger.

  • Neural Networks as Nonlinear Adaptive Filters Perspective Neural networks, in particular recurrent neural networks, are cast into the framework of nonlinear adaptive filters. In this context, the relation between recurrent neural networks and polynomial filters is first established. Learning strategies and algorithms are then developed for neural adaptive system identifiers and predictors. Finally, issues concerning the choice of a neural architecture with respect to the bias and variance of the prediction performance are discussed....

  • Bayesian Estimation Theory: Basic Definitions Bayesian Estimation The Estimate–Maximise Method Cramer–Rao Bound on the Minimum Estimator Variance Design of Mixture Gaussian Models Bayesian Classification Modeling the Space of a Random Process Summary B ayesian estimation is a framework for the formulation of statistical inference problems. In the prediction or estimation of a random process from a related observation signal, the Bayesian philosophy is based on combining the evidence contained in the signal with prior knowledge of the probability distribution of the process.

  • So far, economic fluctuations have been predicted almost exclusively through the aggregate infor- mation conveyed either by i) macro variables (labor market conditions, money, credit, lagged growth), ii) financial indicators (aggregate stock market returns and variances, slope of the yield curve, credit spreads) or iii) confidence (households or business) indicators.
