An extension of bayesian measure of information to regression

This paper extends Lindley's measure of average information to the linear model, E(Y∣ß) = Xß. An expression which quantifies the average amount of information provided by the nxl vector of observations Y about the pxl vector of coefficient parameters ß will be derived. The effect of the structure of the regressor matrix, X, on the information measure is discussed. An information theoretic optimal design is characterized. Some applications are suggested.     

A note on shrinkage factors in two stage testimation

We obtain a simple and natural testimator which has locally, at the parametric point corresponding to the prior knowledge, a smaller mean squared error than any other two stage testimator of a location or a scale parameter of an arbitrary distribution.     

Towards a policy for aging in India

India has been engaged in developing the National Policy for elderly for the last two decades. The efforts to establish a policy began building on traditional values, a small number of pre-independence enactments. Lawgivers of India spoke of the rights of the elderly and the responsibility of the state towards them almost 2000 years ago. Additional factors such as culture, social norms, and influence of international organizations, particularly the Vienna Plan of Action, have been responsible for shaping the Policy. The Plan of Action agreed upon at the end of the Vienna meeting could not come into being due to several reasons such as the size of the country and its federal structure. This article takes an overview of the efforts made by the federal government and the NGOs to create a National Policy. The article describes the process by which the National Policy came into being and provides an overview and critique of the present Policy. The author makes a summary of the major areas of action suggested by the Policy, the strategies designed, and the implementation roles of different Ministries. The author describes the steps taken since 1999 and provides the concluding remarks.     

Are Life Insurance Holdings Related to Financial Vulnerabilities?

Using the 1995 Survey of Consumer Finances and an elaborate life-cycle model, we quantify the potential financial impact of each individual's death on his or her survivors and measure the degree to which life insurance moderates these consequences. Life insurance is essentially uncorrelated with financial vulnerability at every stage of the life cycle. As a result, the impact of insurance among at-risk households is modest, and substantial uninsured vulnerabilities are widespread, particularly among younger couples. We also identify a systematic gender bias: For any given level of financial vulnerability, couples provide significantly more protection for wives than for husbands. (JEL D10 , G22 )     

On the Hypothesis of No Interaction on a Linear Scale in Contingency Tables

The purpose of this paper is to review briefly the three main formulations of no Interaction hypotheses in contingency tables and to consider the formulation on a linear scale in some detail.More specifically we (i) present a situation in 2×2 tables where such a formulation may be more appropriate than others, (ii) study the geometry for this problem, (iii) give contrast-type or parametric ANOVA type formulations in the general n-dimensional tables, (iv) discuss estimation and testing procedures and (v) consider collapsibility of contingency tables in relation to the hypotheses of no interaction on a linear scale.     

The minimum discrimination information approach in analyzing categorical data

A brief review of the minimum discrimination information (MDI) approach in analyzing categorical data is presented in a question -answer format, An example is given to bring out situations in which the MDI approach is more useful. No new results are proved.
