The study of statistical theory and its application on evidence tisting

The evidence test with quantitative characteristic can convert to the problem of statistics theories with twosample average vector and covariance matrix testing at the same time.The thesis〔1,2〕gives us an statistics quantity λ4.However,no one can provied its distribution and application.This thesis uses the method of statistical simulation to give us the experience distribution,and then work out the λ4 distribution table and its error table,apply it to the evidence test.Finally,this thesis provides one practical cases.
