An investigation of multivariate adaptive regression splines for modeling and analysis of univariate and semi-multivariate time series systems
(Monterey, California. Naval Postgraduate School, 1991-09)
This dissertation investigates the use of multivariate adaptive regression splines (MARS), due to Friedman, for nonlinear regression modeling and analysis of time series systems. MARS can be conceptualized as a generalization ...
An investigation of nonlinear controls and regression-adjusted estimators for variance reduction in computer simulation.
(Monterey, California. Naval Postgraduate School, 1991-03)
This dissertation develops new techniques for variance reduction in computer simulation. It demonstrates that applying nonlinear transformations to control variables can increase their effectiveness over linear controls. ...
A type calculus for mathematical programming modeling languages
(Monterey, California. Naval Postgraduate School, 1990-09)
The issue of model validation is critical in the formulation and interpretation of mathematical programming models, yet this problem is largely ignored by contemporary modeling languages and the systems they support. This ...
