| 摘 要： | Testing equality of covariance matrix has long been an interesting issue in statistics inference, To overcome the sparseness of data points in high-dimensional space and deal with the general cases, the author suggests several projection pursuit type statistics. Some results on the limiting distidbutions of the statistics are obtained. Some properties of bootstrap approximation are investigated. Furthermore, for computational reasons an approximation for the statistics based on number-theoretic roethod is applied. Several simulation experiments are performed.

| Abstract: | Testing equality of covariance matrix has long been an interesting issue in statistics inference. To overcome the sparseness
of data points in high-dimensional space and deal with the general cases, the author suggests several projection pursuit type
statistics. Some results on the limiting distributions of the statistics are obtained. Some properties of bootstrap approximation
are investigated. Furthermore, for computational reasons an approximation for the statistics based on number-theoretic method
is applied. Several simulation experiments are performed.
