An update to experimental models for validating computer technology Local xxx chatline tucson
(out-of-sample forecasting) How can agent-based researchers provide summary reports of empirical validation results to other researchers and to intended model users in an accurate, compelling, and clear manner?What to do, in particular, when outcome distributions rather than point predictions are the main findings of a study?Through several case study problems from industrial and scientific research laboratory applications, Mathematical and Experimental Modeling of Physical and Biological Processes provides students with a fundamental understanding of how mathematics is applied to problems in science and engineering.For each case study problem, the authors discuss why a model is needed and what goals can be achieved with the model. Should agent-based modelers strive to achieve all four aspects? Do the following four validation aspects, considered as a whole, provide a complete and comprehensive definition of empirical validation?Input Validation: Are the exogenous inputs for the model (e.g., functional forms, random shock realizations, data-based parameter estimates, and/or parameter values imported from other studies) empirically meaningful and appropriate for the purpose at hand?Process Validation: How well do the physical, biological, institutional, and social processes represented within the model reflect real-world aspects important for the purpose at hand?
Predictive Output Validation: How well are model-generated outputs able to forecast distributions, or distribution moments, for sample data withheld from model identification or for new data acquired at a later time?Exploring what mathematics can reveal about applications, the book focuses on the design of appropriate experiments to validate the development of mathematical models.
