| Abstract | Estimating the tail index of a heavy-tailed distribution depends on the choice of the number k of upper order statistics used in the estimation. In this paper, we reviewed estimating tail index of the heavy-tailed distribution historic course. We summarized selecting k from the heavy-tailed index to the research state and discussed the sum-plot method and bootstrap method of selecting k from heavy-tailed index estimating in detail. And improved the bootstrap method which proposed by Hall, which is called the M-bootstrap method. And we used the above three methods to carry on the Monte-Carlo simulation to the known heavy-tailed distribution, studied their feasibility, compared them with their robust. The results of these three methods are satisfied. Sum-plot method and M-bootstrap method arenpsilat impacted by outliers. Afterwards we made empirical analysis based on Shanghai Stock Index and Shenzhen Component Index data, the computed result indicated that Shanghai Stock Index and Shenzhen Component Index returns ratio is thick-tailed and expose right skew, right tail heavier on left tail. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
