NOTICE Prof. Narinder Kumar of the Department of Statistics, Panjab University, Chandigarh will be visiting the Department during April 2527, 2016 Under the DSA PhaseII Visiting Scientist program. As part of the visit, Prof. Kumar will deliver two lectures. The details of the lectures are as follows: Lecture 1: Certain Aspects of Statistical Theory and Related Applications (This lecture is intended for students) Date & time: Tuesday, April 26, 2016 at 2:45 p.m. Venue: Departmental Seminar Room Lecture 2: On the Choice of the Best among Several Populations Date & time: Wednesday, April 27, 2016 at 3 p.m. Venue: Departmental Meeting Room Abstract In many practical situations the problem of subset selection is used. For example, a business concern using different advertising methods to enhance the sales prefers the advertising methods with more consistent sales among the methods having the same average yields. Likewise, in agriculture when the average yield of all the variables of a crop is same, the aim is to select more consistent varieties to be recommended for small and marginal farmers. Similarly in animal husbandry more consistent breeding methods are preferred among the breeding methods with the same average. In all of the above situations, the need is to develop subset selection procedures to select a subset of the populations which includes the best population. The best population, under the above formulations, is the one with the least variability. In literature, there are several approaches which deal with this area. In the present work, some approaches which are widely used are discussed. We develop a selection procedure, and tables of critical constants which are necessary to carry out the procedure are worked out. Performance of the proposed procedure in comparison to the existing procedure is assessed through simulation study. The proposed procedure is also illustrated with the help of a real life example. Key words and phrases: Best Population; Probability of Correct Selection; Expected Subset Size; Simulation Study. All are cordially invited to attend.

NOTICE Prof. Dilip C. Nath of the Department of Statistics, Gauhati University, Assam will be visiting the Department during April 2526, 2016 Under the DSA PhaseII Visiting Scientist program. As part of the visit, Prof. Nath will deliver two lectures. The details of the lectures are as follows: Lecture 1: Representativeness of Ranked Set Sampling in Estimation of Population Proportion (based on joint work with Vivek Verma, & Radhakanta Das) Date & time: Tuesday, April 26, 2016 at 12:30 p.m. Venue: Departmental Meeting Room Abstract One of the main objectives after the selection of a sample through a sampling procedure is to know whether the obtained samples represent the population or not. This article discusses about the problem of comparing representativeness of samples in the estimation of unknown population proportion (p) of certain characteristics of a dichotomous population. Here samples are obtained through the technique of Ranked Set Sampling (RSS) and Simple Random sampling (SRS). The proposed procedure is also illustrated via a reallife data set of children below 3 years of age and our interest lies in estimation of proportion of them who are not currently nourished with mother’s milk. The comparison among the samples of SRS and RSS is done through the relative precision of the estimates (maximum likelihood and Bayes) and by comparing the Bscores obtained through Bayesian sets. The findings reveal that the estimate of proportion obtained using ranked set sample is found to be more efficient and representative of the population when the probability of success is considerably smaller. Lecture 2: New Ageing Indices: An Application of Measuring Aging Process of Some Asian Countries with Special Reference to Bangladesh Population (This lecture, based on joint word with M. Nazrul Islam, is intended for students) Date & time: Tuesday, April 26, 2016 at 2 p.m. Venue: Departmental Seminar Room Abstract Commonly used aging measures such as proportion of aged person, proportion of persons aged less than fifteen years, aging index (agedchild ratio) are based on simple head count ratio (HCR). HCR is a crude measure as it fails to give any idea about the tail distribution of population age. Here an attempt has been made to develop new aging indices (age gap, age distribution sensitive and generalized) taking into account both tails of population age distribution i.e., distribution of population aged under fifteen and sixty or more. These new indices have been applied to Bangladesh population based on data collected from secondary sources: UN international data base; International Data Base, US Census Bureau and Bangladesh Bureau of Statistics (BBS), for the year 1961, 1981 and 2001. Conventional aging indices have also been calculated and compared with new ones. Crosscountry analysis has also been performed to study the sensitivity of aging indices. Analysis shows an increasing aging process and new indices indicate the process faster than conventional ones. For example, relative increases of aging process in 2001 compared to 1981 for conventional and new aging indices (agedyoung age gap and agedyoung distribution sensitive) are 28.97, 39.19 and 42.04 percent respectively. The findings also indicate that population aging in the peak is not clear but in the base it is evident. Again aging process with respect to sex and urbanrural is also different. From crosscountry analysis it is found that new indices are more sensitive than conventional ones. All are cordially invited to attend.

Prof. Asha Gopalkrishnan of the Department of Statistics, Cochin University of Science & Technology (CUSAT), Kerala will be visiting the Department during March 2731, 2016 Under the DSA PhaseII Visiting Scientist program. As part of the visit, Prof. Gopalkrishnan will deliver two lectures. The details of the lectures are as follows: Lecture 1: ON MODELLING SYSTEMS WITH CASCADING FAILURES Abstract The notion of cascading failures is a common phenomenon we observe around us. Here the initial failure alters the structure function of the system, which leads to subsequent failures within a short period of time referred to as threshold time. Freund (1961, A bivariate extension of the exponential distribution. Journal of the American Statistical Association, 56(296): 971977) introduced an exponential distribution that allows modeling a parallel redundant system with two components. In this system the life time of the two components behave as if they are independent, until one of the components fails, after which the remaining component suffers increased/decreased stress. This model has been extended by Swift A. W (2008, Stochastic models of cascading failures. Journal of Applied Probability. 45(4): 907921) to model cascading failures. A further generalization using the proportional hazards model for component failures, its various properties and statistical inference procedure will be discussed. Date & time: Monday, March 28, 2016 at 4 p.m. Lecture 2: RELIABILITY PROPERTIES OF AGE REPLACEMENT MODELS Abstract In this talk some basic reliability properties of an age replacement model will be discussed. Relationships between the mean time to failure (MTTF) of an age replacement model , its hazard rate and mean residual life will be revisited. An ordering based on MTTF of an age replacement model along with its implications on other existing orders will also be discussed. Date & time: Wednesday, March 30,2016 at 3 p.m.
All are cordially invited to attend.

Title: Independent Component Analysis in the presence of unknown correlated Gaussian noise
Speaker: Prof. Rajesh Ranjan Nandy, University of North Texas, USA
Date and time: Monday, December 07, 2015 at 4:30 p.m.
Venue: Seminar Room, Department of Statistics, University of Calcutta
Abstract
Independent Component Analysis (ICA) is a computational method for separating a multivariate mixed signal into its original nonGaussian sources. ICA algorithms were originally developed in the absence of any noise in the model and have later been extended with some success to incorporate the presence of white noise. However, no ICA algorithm has been developed so far for mixed signals in the presence of correlated noise with unknown covariance structure. A novel algorithm will be presented to solve this problem, where the conventional nonnoisy ICA will be used to first estimate the number of independent sources and then to estimate the noise covariance matrix under the weak assumption of stationarity for the noise. Results will be presented using simulated data where it will be established that the proposed method provides superior extraction of original sources compared to nonnoisy ICA algorithms as well as noisy ICA algorithms with white noise. All are cordially invited.

The particle starts at 0 and thereafter at each step it moves to the adjacent vertex, going clockwise with a known probability p, or counterclockwise with probability 1. The directions of successive movements are independent. What is the expected number of moves needed (1) to return to 0, (2) to visit all vertices, (3) to return to 0 after visiting all vertices? We answer these and other related questions using recursive relations. Date and time: 4 p.m., on Thursday, July 16, 2015.
