Managerial communication/conversation in organizations is difficult to capture in its complexities.
Even if attempts are made, the outcome is rarely, if ever, natural and spontaneous. How then do we
proceed with an ...
Confidence interval of two independent binomial proportions using weighted profile likelihood
(Communications in Statistics - Simulation and Computation, 2008-11-11)
Interval estimation of the difference of two independent binomial proportions is an important problem in many applied settings. Newcombe (1998) compared the performance of several existing asymptotic methods, and based on ...
Bayesian analysis of the change-point problem for directional data
(Journal of Applied Statistics, 2008-11-11)
In this paper, we discuss a simple fully Bayesian analysis of the change-point problem for the directional data in the parametric framework with von Mises or circular normal distribution as the underlying distribution. We ...
A likelihood integrated method for exploratory graphical analysis of change-point problem with directional data
(Communications in Statistics, Theory and Methods, 2008-11-11)
In this article we introduce a new likelihood based method, called the likelihood integrated method, which is distinct from the well-known integrated likelihood method. We use the likelihood integrated to propose a simple ...
