On Multiple Hypothesis Testing with Rejection Option
We study the problem of multiple hypothesis testing (HT) in view of a
rejection option. That model of HT has many different applications. Errors in
testing of M hypotheses regarding the source distribution with an option of
rejecting all those hypotheses are considered. The source is discrete and
arbitrarily varying (AVS). The tradeoffs among error probability
exponents/reliabilities associated with false acceptance of rejection decision
and false rejection of true distribution are investigated and the optimal
decision strategies are outlined. The main result is specialized for discrete
memoryless sources (DMS) and studied further. An interesting insight that the
analysis implies is the phenomenon (comprehensible in terms of
supervised/unsupervised learning) that in optimal discrimination within M
hypothetical distributions one permits always lower error than in deciding to
decline the set of hypotheses. Geometric interpretations of the optimal
decision schemes are given for the current and known bounds in multi-HT for
AVS's.Comment: 5 pages, 3 figures, submitted to IEEE Information Theory Workshop

Attitudes towards old age and age of retirement across the world: findings from the future of retirement survey
The 21st century has been described as the first era in human history when the world will no longer be young and there will be drastic changes in many aspects of our lives including socio-demographics, financial and attitudes towards the old age and retirement. This talk will introduce briefly about the Global Ageing Survey (GLAS) 2004 and 2005 which is also popularly known as “The Future of Retirement”. These surveys provide us a unique data source collected in 21 countries and territories that allow researchers for better understanding the individual as well as societal changes as we age with regard to savings, retirement and healthcare. In 2004, approximately 10,000 people aged 18+ were surveyed in nine counties and one territory (Brazil, Canada, China, France, Hong Kong, India, Japan, Mexico, UK and USA). In 2005, the number was increased to twenty-one by adding Egypt, Germany, Indonesia, Malaysia, Poland, Russia, Saudi Arabia, Singapore, Sweden, Turkey and South Korea). Moreover, an additional 6320 private sector employers was surveyed in 2005, some 300 in each country with a view to elucidating the attitudes of employers to issues relating to older workers. The paper aims to examine the attitudes towards the old age and retirement across the world and will indicate some policy implications
