Abstract:
To study local influence of the data cases on the Score statistic for the test of varying dispersion in the nonlinear model of simplex distribution, this paper develops the local influence on the score test statistic under perturbat ion in the response variable and explanatory variables based on gradient method. The corresponding d-i agnostic stat istics for measuring the maximum local influence are obtained. At the end, the influence cases in the ophthalmology study data are obtained based on the statistics derived in the paper, and the result demonstrates that the method in the paper is effect ive.
