Power Akash Distribution and Its Application
Rama SHANKER, Kamlesh Kumar SHUKLA
A two-parameter power Akash distribution (PAD), which includes Akash distribution introduced by Shanker (2015) as a particular case, has been proposed and its important statistical properties including shapes of the density, hazard rate function, moments, skewness and kurtosis measures, and stochastic ordering have been discussed. The maximum likelihood estimation has been discussed for estimating its parameters. Finally, the goodness of fit PAD has been discussed with a real lifetime data set from engineering and the fit has been found better as compared with two-parameter power Lindley distribution (PLD) and one parameter Akash, Lindley and exponential distributions.
Sustainable Tourism in Campania Region: Statistical Analysis and Metrics for the Development of Tourist Destinations
Vincenzo BASILE, Massimiliano GIACALONE
This paper deals with the issue of the sustainable tourism in Campania region and its touristic offer in the four territorial clusters: art cities, marine, thermal and hilly locations. In the paper it is pointed out that the way the regional authorities incentivize or assist farms to diversify into tourism may have implications for sustainability, examined in this study by the presence of 11 indicators. The Global Tourist Index (G) was estimated by the Global Tourism Index (G) for the region, obtained from the combination of structural variables (number of accommodation facilities and of beds) and of flows (arrivals and presences) registered in Campania tourism. Finally, some emerging territorial strategies are proposed for the integrated development of a tourist system in the Campania Region. That is, the tourist destinations and the territorial brand. The final aim of this research is to develop and test a global index (appropriately modified) for sustainable development in tourism industry context to address the integration of social, economic, and ecological elements of sustainable development and the contextual nature of sustainable development.
Robust Control Charts for Process Dispersion Based on Jackknife Estimates
M. R. SINDHUMOL, M. GALLO, M. R. SRINIVASAN
Control chart is a powerful technique that can be of immense use in an industrial process in many ways like detecting assignable causes of variation from a target value, or giving an early warning on quality deterioration, or identifying outliers, or a continuous monitoring of the process. There are many parametric and nonparametric methods of developing control limits, in the literature. This article provides two general nonparametric procedures to develop dispersion control charts. First one is a general method to develop robust control limits using jackknife samples and the latter, is based on confidence intervals using jackknife sampling methods. Performance comparison of these limits is studied on simulated data. Average Run Length is also considered for comparison.
Correspondence Analysis of the Volunteer in Romania
The present paper proposes a characterization of the Romanian volunteer according to socio-demographic and economic characteristics. Volunteering is unpaid work. Although it is an activity for which volunteers do not receive material benefits in return, they have other benefits. However, not every person is eager to spend time on such an activity. In order to characterize the Romanian volunteer, a survey was realized among them, recording variables, both socio-demographic and economic. As method, was used factorial analysis of variables using SPSS. According multiple correspondence analysis, it was concluded that the male volunteer differs from the female one, having different characteristics regarding studies, financial position, marital status, type of family, time since he activates as a volunteer and age.
