Data Fusion of Small Sample Flying Test Data and Big Sample Simulation Test Data Based on Equivalent Sample for Equipment Efficiency Evaluation

How to fuse the small flying test data and the big simulation test data is such a difficult research hot in small sample data solution field. Bayesian formula is usually adopted to solve this problem, but when it is used directly, the simulation test data always drowns the flying test data. To solve the above problem, an improved Bayesian formula for static data fusion is put forward based on simulation equivalent flying sample, which introduces the crediblity degree in forms of equivalent flying sample to Bayesian formula. And at the same time, we give out an analysis of theory and applications counter measures. The numerical computations show the feasibility of the improved method.
