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-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 ...
