    Abstract: Gender statistics is an area that cuts across traditional fields of statistics to identify, produce and disseminate statistics that reflect the realities of the lives of women and men, and policy issues relating to gender. This paper studies women empowerment as a powerful instrument for national transformation and sustained economic growth. Attemp... Show More

    Abstract: In the present communication information theoretic dependence measure has been defined using maximum entropy principle, which measures amount of dependence among the attributes in a contingency table. A relation between information theoretic measure of dependence and Chi-square statistic has been discussed. A generalization of this information theo... Show More

    Abstract: The aim of the study was to formulate a Time Series Model to be used in obtaining optimal estimates of miss-ing observations. State space models and Kalman filter were used to handle irregularly spaced data. A non-Bayesian ap-proach where the missing values were treated as fixed parameters. Simulated AR (1) data and corresponding estimated missing ... Show More

    Abstract: In multivariate outlier studies, the sum of squares and cross-product (SSCP) is an important property of the data matrix. For example, the much used Mahalanobis distance and the Wilk's ratio make use of SSCP matrices. One of the SSCP matrices involved in outlier studies is the matrix for the set of multiple outliers in the data. In this paper, an e... Show More

    Abstract: Comparing the order statistics of daily returns of the S&P 500 index from 03.01.1950 to 04.03.2013 with the corresponding rankits, a linear scale dilation is observed. This observation is used to derive a five-parameter density function for the parsimonious description of the unconditional distribution of stock returns. The typical graph of this de... Show More
