Guidelines for Estimation of Non-Linear Least Squares Power Functions and Upper Limit Curves,

摘要

A non-linear least squares procedure for estimating power function coefficients is presented in this report. A procedure is recommended for obtaining associated prediction and tolerance upper limit curves. A technique to prevent outlier caused distortions in mean power functions and upper limit curves caused by outliers is also described. This report should be used as a user's guide at the Naval Air Test Facility (NATF) for generating power functions and upper limit curves. Examples given in this report provide practitioner handy checkout guides. Rationale and justification underlying recommended procedures are given in Report NATF-COS-6, Application of Non-Linear Least Squares Procedures to Power /Functions and Upper Limit Curves. (Author)
