I am planning to develop efficient semiparametric approaches to univariate and multivariate regression and density estimation and to study related convergence issues. A recently proposed differentiated logdensity approximant, which turns out to possess numerous desirable properties, requires further investigation. I shall extend my results on the distribution of the distance between random points located in rectangles, polygons and parallelepipeds to random points located in polygonal pyramids, and consider certain applications to transportation logistics, such as those associated with intercity traffic and the positioning of airtankers. Further developments on generalized distributions should lead to more efficient techniques in reliability analysis and quality control. The Bayesian predictive approach will be used to make inferences in connection with problems arising in the biomedical fields, and in particular, in statistical genetics. Extensions of the published distributional results in Time Series to general ARMA models are also being investigated. I intend to explore an alternative structural representation of elliptically contoured distributions; promising applications include the modelling of time series with thick-tailed distributed innovations as well as the development of efficient alternative techniques for simulating functions involving elliptically contoured vectors, among others. I shall develop efficient algorithms for determining the distribution function of indefinite quadratic forms in singular elliptically contoured or complex random vectors. I shall make the code associated with several of my results available on Wolfram's website. I am also preparing monographs on density estimation and Hermitian quadratic forms. Finally, I am aiming to complete a textbook on multivariate statistical analysis with the addition of chapters on classification, multivariate analysis of variance and generalized linear models.

我计划开发有效的半参数方法，单变量和多变量回归和密度估计，并研究相关的收敛问题。最近提出的微分对数密度近似，它原来具有许多理想的属性，需要进一步的调查。我将把我关于矩形、多边形和平行六面体中随机点之间距离分布的结果推广到多边形金字塔中的随机点，并考虑在运输物流中的某些应用，例如与城际交通和空中加油机定位有关的应用。广义分布的进一步发展，将导致更有效的技术在可靠性分析和质量控制。贝叶斯预测方法将用于与生物医学领域，特别是统计遗传学中出现的问题有关的推断。扩展的时间序列一般阿尔马模型的分布结果也正在调查。我打算探索一种替代的结构表示的椭圆轮廓分布，有前途的应用包括建模的时间序列厚尾分布的创新，以及开发高效的替代技术，用于模拟功能，涉及椭圆轮廓向量，等等。我将开发有效的算法来确定分布函数的不定二次型奇异椭圆轮廓或复杂的随机向量。我将在Wolfram的网站上提供与我的几个结果相关的代码。我也在准备关于密度估计和厄米特二次型的专著。最后，我的目标是完成一本关于多元统计分析的教科书，增加分类，多元方差分析和广义线性模型的章节。
