New modeling methods of multi-batch test data

In order to meet the accuracy of mathematical modeling,as required by sensor accuracy analysis,this paper proposes two new different modeling methods of multi-batch test data,namely,mathematical statistics modeling method and average parameters modeling method.The application of the methods to modeling electric eddy sensor's multi-batch test data,and comparison with least square method on the accuracy of fitted sensor prove the accuracy of the mathematical statistics modeling method designed for sensor accuracy analysis and the simplicity of average parameters modeling method.
