A metamodel is a relatively small, simple model that approximate the “behavior” of a large, complex model. A common way to develop a metamodel is to generate “data” from a number of largemodel runs and to then use off-the-shelf statistical methods without attempting to understand the model’s internal workings. It is much preferable, in some problems, to(More)
The objective of exploratory analysis is t o gain a broad u n d e r s tanding of a p rob lem domain before going into details for pa r ticular cases. Its focus is unders tand ing comprehensively the consequences of u ncertainty, which requires a good deal more than normal sensitivity analysis. Such analysis is facilitated by multiresolution, m u l t i p e r(More)
Over the last decade, we and colleagues have done considerable theoretical and applied work involving multiresolution modeling and exploratory analysis,1 in part to connect the worlds of strategic planning (e.g., development of the defense guidance and defense programs) 2 with the world of more detailed analysis (e.g., development of military forces, weapon(More)
Exploratory analysis uses a low-resolution model for broad survey work. High-resolution simulation can sometimes be used to inform development and calibration of such a model. This paper is a case history of such an effort. The problem at issue was characterizing the effectiveness, in interdicting an invading army, of long-range precision fires. After(More)
