Key Findings Crude rates depict the true magnitude of the risk as an average measure at the total population level. However, they are heavily affected by the respective age composition of the populations being compared. Once standardised for age composition, the rates become comparable. However, the standardised rates are hypothetical. In all cancer incidence for example, they are not the true ...

This paper uses the method of cross spectral analysis to examine preand post-1987 crash comovements among several Pacific Rim markets. The results support increased post-crash comovements among the markets. Each of the pairwise median coherences was greater in the post-crash period. The same is true for the post-crash mean coherences, with one exception. The nonparametric Wilcoxon Z statistics ...

This manuscript provides extended statistical tables, a numerical example with detailed calculations and Fortran code in conjunction with the paper entitled ”On testing the mean equivalence of treatments from correlated normal populations” by Chen, Hubert J, Wu, Shu-Fei and Wang, WenGine. Let there be k equally correlated treatment populations under consideration, a Studentized range test is pr...

It is argued that the present log-normal distribution of language sizes is, to a large extent, a consequence of demographic dynamics within the population of speakers of each language. A two-parameter stochastic multiplicative process is proposed as a model for the population dynamics of individual languages, and applied over a period spanning the last ten centuries. The model disregards langua...

In this paper, we consider the problem of partitioning a small data sample drawn from a mixture of k product distributions. We are interested in the case that individual features are of low average quality γ, and we want to use as few of them as possible to correctly partition the sample. We analyze a spectral technique that is able to approximately optimize the total data size—the product of n...

Although overcrowded and the depopulation of the population are one of the social issues in Japan, the complex mechanisms are not comprehended. Then, we tried to show this phenomenon by catching as a network. We interpreted prefectures as nodes and migration as links. We observe power law distribution in both population and migration. We insist on the necessity of reconsider the prevailing assu...

Objective(s): Short tandem repeat (STR) loci are the most informative DNA genetic markers for attempting to individualize biological material for application in paternity and forensic cases. Materials and Methods: Blood samples were collected and the total genomic DNA was extracted. The DNA samples were used for genotyping VWA and TPOX STR loci using PCR and polyacrylamide gel electrophoresis. ...
