Initial evaluation of the modified step-wise regression procedure to estimate aircraft stability and control parameters from flight test data

摘要

This report presents the initial results of research in progress in the College ofAeronautics at the Cranfield Institute of Technology. The object of the research is toinvestigate the use of the Modified Stepwise Regression procedure to estimate aircraftstability and control parameters from flight test data.The Stepwise Regression Method for parameter identification is a procedure that insertsindependent variables into a regression model. Each time a new variable is added to themodel a regression is performed and the fit is examined when the new variable, or anyother previously included variable, may be rejected from the model if non-significant to thefit. The iterative process continues until a satisfactory fit (or model) is obtained.
