Application of Regression Analysis to Hardware Cost Estimation

摘要

The report presents an example of regression analysis which illustrates the major judgmental considerations in the development of a cost estimating relationship. The example used is the development of hardware costs of turbine aircraft engines. The methodology discussed is most useful for 'quick reaction' studies and has been used by Headquarters, US Army Materiel Command for this purpose. Particular points discussed are: scatter diagrams, net scatter diagrams, causal requirements, combinations of variables, and sample selection. (Author)
