Credit off-take from formal financial institutions in rural India: quantile regression results
(Springer Science+Business Media, 2014)
Extending financial services to unbanked population in India has remained a central part of the policy thrust of the Indian government for decades. To that effect, a widespread formal credit delivery mechanism has been ...
SB-robust estimators of the parameters of the wrapped normal distribution
(Communications in Statistics: Theory & Methods, 2013)
In this article, we study the SB-robustness of various estimators of the mean direction (μ) and the concentration parameter (ρ) of the wrapped normal distribution. The functional corresponding to the sample mean direction ...
Response-adaptive allocation for circular data
(Taylor & Francis, 2014)
Response-adaptive designs are used in phase III clinical trials to allocate a larger proportion of patients to the better treatment. Circular data is a natural outcome in many clinical trial setup, e.g., some measurements ...
SB-robustness of directional mean for circular distributions
(2011-09-07)
In this paper we study the robustness of the directional mean (a.k.a. circular mean) for
different families of circular distributions. We show that the directional mean is robust
in the sense of finite standardized gross ...
SB-robust estimator for the concentration parameter of the circular normal distribution
(Statistical Papers, 2012)
In this paper we discuss robust estimation of the concentration parameter ( κ) of the circular normal (CN) distribution. It is known that the MLE of the concentration parameter is not B-robust at the family of all circular ...
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 ...
A robust sharpe ratio
(Sankhya B : The Indian Journal of Statistics, 2019)
Sharpe ratio is one of the widely used measures in the financial literature to compare two or more investment strategies. Since it is a ratio of the excess expected return of a portfolio to its standard deviation of returns, ...
Interval-valued data analysis
(International Journal of Business Analytics and Intelligence, 2015-10)
