Creating and sustaining excellence in Indian academic institutions: some thoughts
(Association of Indian Universities, 2018-10)
For over 20 years, i have read articles in newspapers and magazines by Indian academicians, mostly academic administrators, habitually bemoaning the 'absence' of quality education in the country.They have periodically ...
Robustness of tests for directional mean
(Taylor & Francis, 2015)
In this paper we study the robustness of the likelihood ratio, circular mean and circular trimmed mean test functionals in the context of tests of hypotheses regarding the mean direction of circular normal and wrapped ...
Sectoral credit choice in rural India
(Elsevier, 2015)
This article examines the question, what makes a rural household a preferred choice for formal lenders? A sample selected ordered probit model is developed to address this question. While the selection equation models the ...
Interval-valued data analysis
(International Journal of Business Analytics and Intelligence, 2015-10)
Real time location prediction with taxi-GPS data streams
(Transporation Research Part C: Emerging Technologies, 2017-07)
The prediction of the destination location at the time of pickup is an important problem withpotential for substantial impact on the efficiency of a GPS-enabled taxi service. While this pro-blem has been explored earlier ...
Comparison of treatments in a cataract surgery with circular response
(Sage, 2015)
Circular data are a natural outcome in many biomedical studies, e.g. some measurements in ophthalmologic studies, degrees of rotation of hand or waist, etc. With reference to a real data set on astigmatism induced in two ...
A novel sandwich algorithm for empirical Bayes analysis of rank data
(International Press, 2017)
Rank data arises frequently in marketing, nance, organizational
behavior, and psychology. Most analysis of rank data reported in the
literature assumes the presence of one or more variables (sometimes
latent) based on ...
SB-robust estimation of mean direction for some new circular distributions
(Springer, 2016)
The most often used distribution for modelling directional data has been the
circular normal (CN) (a.k.a. von-Mises) distribution. Recently Kato and Jones (K–J)
introduced a family of distribution which includes the CN ...
Distribution of traffic accident times in India - some insights using circular data analysis
(2017)
Traffic accidents are a major hazard for travellers on
Indian roads. These are caused by a variety of reasons
including the bad condition of roads, traffic density, lack
of proper training of drivers, slack in enforcement ...
Clustering and classification of time series using topological data analysis with applications to finance
(Expert Systems with Applications, 2020-08-15)
In this paper, we propose new methods for time series classification and clustering. These methods are based on techniques of Topological Data Analysis (TDA) such as persistent homology and time delay embedding for analysing ...
