| Abstract | The problem of hypothesis testing, which is to decide between two alternative explanations for the observed data, is one of the standard problems in statistics. A discrete memoryless source (DMS) is a sequence of i.i.d random variables. The distribution of the DMS is either P/sub 1/ or P/sub 2/. When a sample is emitted from the source, the observer attempts to decide which hypothesis of H/sub 1/:P/sub 1/ or H/sub 2/:P/sub 2/ is correct. The main concern of this problem is to determine the best asymptotic exponent of the second kind of the error probability when the first kind of the error probability is (1) fixed (2) less than 2/sup -nr/. These are specified by (1) the well-known lemma of Stein (Blahut 1974) the theorem of Hoeffding (1965), Blahut (1974), Csiszar and Longo (1971) for the hypothesis testing problem with exponential-type constraint. DMS is an ideal model. A more robust model is an arbitrarily varying source (AVS), where the source distribution may vary within a certain set of distribution from one time instant to the next. The varying behavior of the distribution of AVS is not known exactly, and there are only two alternatives. We consider the problem of hypothesis testing for AVS in the same way for DMS, and determine the best asymptotic exponent of the second kind of the error probability when the first kind of the error probability is (1) fixed (2) less than 2/sup -nr/. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
