A Matching Prior for the Shape Parameter of the Skew‐Normal Distribution

Abstract. This paper deals with the issue of performing a default Bayesian analysis on the shape parameter of the skew‐normal distribution. Our approach is based on a suitable pseudo‐likelihood function and a matching prior distribution for this parameter, when location (or regression) and scale parameters are unknown. This approach is important for both theoretical and practical reasons. From a theoretical perspective, it is shown that the proposed matching prior is proper thus inducing a proper posterior distribution for the shape parameter, also when the likelihood is monotone. From the practical perspective, the proposed approach has the advantages of avoiding the elicitation on the nuisance parameters and the computation of multidimensional integrals.     

墨西哥乡村地区旅游发展研究——以尤卡坦地区艾克巴兰村为例

在墨西哥坎昆—玛雅海岸走廊后方的内陆地区,有一些村落凭借优越的地理位置以及丰富多样的地形地貌、生物种类和社会文化发展旅游业,开展有别于传统旅游产品的业务。当地政府力求通过发展旅游业来促进乡村地区的经济发展。这些地区围绕“深厚的玛雅文明”与“繁茂的热带雨林”探索,向造访坎昆—玛雅海岸的旅游者推出各种旅游活动以丰富其体验。通过对艾克巴兰村（Ek Balam）案例地的旅游业发展的研究,揭示了当地政府以及居民作为旅游业参与者在旅游化进程中的职能与作用。
