Interpoint Distance Test of Homogeneity for Multivariate Mixture Models

Finite mixtures offer a rich class of distributions for modelling of a variety of random phenomena in numerous fields of study. Using the sample interpoint distances (IPDs), we propose the IPD‐test statistic for testing the hypothesis of homogeneity of mixture of multivariate power series distribution or multivariate normal distribution. We derive the distribution of the IPDs that are drawn from a finite mixture of the multivariate power series distribution and multivariate normal distribution. Based on the empirical distribution of the IPDs, we construct a bootstrap test of homogeneity for other multivariate finite mixture models. The IPD test is applied to mixture models for matrix‐valued distributions and a test of homogeneity for Wishart mixture is presented. Numerical comparisons show that IPD test has accurate type I errors and is more powerful in most multivariate cases than the expectation–maximization (EM) test and modified likelihood ratio test.

Utilizing urban form characteristics in urban logistics analysis: a case study in Lisbon,Portugal

Within the realm of urban logistics, Macário (2013) developed a hypothesis, denominated the Logistics Profile (LP) concept that suggests homogeneous groups of urban zones with respect to three dimensions, which could be used to analyze freight movement policy: (1) the social and built environment; (2) characteristics of the goods/products being moved; (3) characteristics of the deliveries at the receiver establishment. The concept was expected to ease the transferability of best practices in city logistics, by analyzing similarities and differences between zones. This research uses a quantitative methodology to apply the LP concept, and assess its potential, using the city of Lisbon as a case study. The analysis is focused on: (a) the extrapolation of freight trip generation per establishment and delivery characteristics from a sample of commercial establishments to the population within the case study, (b) proposing a methodology to test the LPs, (c) testing the existence of proposed LPs. Freight trips have been extrapolated using a Multiple Classification Analysis (MCA) model. Freight delivery characteristics were attributed to establishments from a sample-based probability distribution. LPs were tested using a two-step cluster analysis. Some LPs have been matched with clusters of case-study zones, subject to case study particularities. Profile overlap was not an issue and occurrences were expected. The testing showed that Logistic Profiles have the potential for being used as a departure point for urban freight planning and policy analysis.

对物质宇宙的爱意与崇仰——兼论唯物主义的智本形态与情本形态

唯物主义理论有着不同的理论形式和形态,这些理论形态或形式随着人类的实践的深入而不断改变。近代工业革命以来,唯物主义建立在牛顿力学的基础上,将自然看作机械的,以开发自然、征服自然为旗帜。但工业革命所带来的环境问题、生态问题在现代则越来越困扰、甚至威胁着人类的生存。唯物主义就必须改变它的内容与形态,以自然之子的态度定位人与物质宇宙的关系,崇仰宇宙、敬畏宇宙,不是从纯粹知的形式,而且也从爱的、情智的关系上理解唯物主义的内涵与唯物主义的新形式。     

Marginal Economy: Growth Strategies for Post-Growth Societies

A sharp problem focus sharpens the problem. Sustainably growing bodies of literature on degrowth are not the key to post-growth scenarios because evocations of the limits of growth reinforce rather than transcend the economic principle, which is in the observation of scarcity. Therefore, I focus on alternative forms of growth rather than alternatives to growth. My form-theoretical analysis of growth dismoralizes growth and disembeds it from the economic medium in which it is preferably drawn. I suggest that the key to a post-growth society is in a regrowth of interest in growth in, so far, neglected non-economic function systems.     

A Reduced‐Form Model for Warrant Valuation

This paper studies warrant valuation using a reduced‐form model. Analogous to the credit risk literature, structural models require complete information about the asset value process and the firm’s liabilities. In contrast, reduced‐form models require only information about the firm’s stock price process. We introduce a reduced‐form model where the warrant holder is a price taker, and we relate our model to structural models appearing in the literature.
