“…The data set consisted of a measure of air quality index (y), the associated temperature (x), and wind direction ( ). Clearly, a linear-circular model is appropriate for this data set, and the methodology proposed by Bhattacharya and SenGupta (2009) seemed to perform satisfactorily. It is to be noted, however, the linear-circular models proposed by Johnson and Wehrly (1978) cannot be handled by the approach of Bhattacharya and SenGupta (2009), and requires ISMCMC or related algorithms.…”

“…This might be done by combining our approach to modeling the marginal distributions of circular variables with copula methods as in e.g., Carnicero et al (2013). Secondly, approaches to regression models, similar to Bhattacharya and SenGupta (2009) where DP mixtures of von Mises distributions were used, or time series, extending the approach of Coles (1998) where wrapped normal distributions to the semiparametric setting might be considered. Finally, it would be interesting to consider extensions to spherical and hyperspherical data which have been analyzed in a classical nonparametric framework using von Mises kernels in e.g., Hall et al (1987).…”

“…4,5 Bu dağılımlar için karma dağılım sayısı bilinmediği durumlarda Dirichlet süreci kullanılarak Bayesci yarı parametrik yöntemlerde önerilmiştir. 15,16 BULGULAR Bu bölümde, tek tepeli, iki-tepeli karma dairesel dağılımlar ve genelleştirilmiş von Mises dağılımla-rını kullanarak, ilk önce DASSD 1 protein veri tabanındaki Alanin amino asitler dizisi (Ala-AlaAla) için dihedral açısı , daha sonra ise su kaplumbağalarının kumsaldan dönüş yönleri verileri analiz edildi. Bu veri setlerinin analizinde açı birimi derece yerine radyan kullanılmıştır, yani derece birimiyle ifade edilen açı değerleri /180 ile çarpılmıştır.…”
