Nonlinear Regression Theory and Computer Programs.

This report presents programs in the FORTRAN V and BASIC computer languages employing a statistical technique to estimate the parameters for nonlinear regression equations. These computer programs could be modified or expanded inthe future to utilize an improved statistical technique or to include additional statistical calculations and output that would provide information to the user. The Naval Weapons Center Weapon Systems Cost Analysis Division develops Cost Estimating Relationships CERs to estimate the relationships between the costs of current and past weapon systems to system physical, performance, and technical parameters. These CERs can be used to predict the costs of future weapons systems. CERs are often regression equations that are nonlinear in the parameters. Author
