Abstract :
We introduce a new wrapped exponential distribution named transmuted wrapped exponential (TWE) distribution, for the
modeling of circular datasets by using the Transmutation Rank-Map method. This method is employed for the first time for
a wrapped distribution with this study. The introduced distribution is more flexible than traditional wrapped exponential
distribution. The paper provides the explicit form of important distributional properties of the introduced distribution such as
expectation, median, moments, characteristic function, quantile function, hazard rate function and stress-strength reliability.
Rényi and Shannon entropies are also obtained. The statistical inference problem for the TWE distribution is investigated
using maximum likelihood, least squares and weighted least squares and comparative numerical study results are presented.
Furthermore, we present a real dataset analysis.
