The subjects of the study are Olympic Games of 1992, 1996 and 200. By use of quantile regression to formulate the econometric model, some variables of the participating countries are taken as independent variables. Variables such as the size of the participating countries, population, economic capacity, construction capacity, globalization and mobility are the examples. It is to explore the effects of the total signal for medal-won numbers when the dependent variable is the principal component, CGW weighted medal-won numbers, and LGdd weighted medal-won numbers.

By means of uniform orthogonal sampling, we represent the shape signature of each model as a statistical distribution of its surface normals weighted by view-dependent depth. The distribution is further processed by spherical harmonics analysis to construct the final representation. By calculating the distance between shape descriptors of individual 3D models, a faithful similarity measurement is achieved.
