The proposed United States FY2013 budget requests $769 million dollars for information security initiatives under the Department of Homeland Security. Projected annual spending for information security exceeds $10 billion by 2015. A new method using validated processes to quantitatively identify risk of a successful cyber attack would allow targeted interventions and a more efficient use of fun...

Impairments in cell migration processes may cause various diseases, among which cancer cell metastasis, tumor angiogenesis, and the disability of immune cells to infiltrate into tumors are prominent ones. Mathematical modeling has been widely used to analyze the cell migration process. Cell migration is a complicated process and requires statistical methods such as random walk for proper analys...

This commentary discusses the Bauer and Curran (2002) investigation of growth mixture modeling. Single-class modeling of non-normal outcomes is compared to modeling with multiple latent trajectory classes. New statistical tests of multiple-class models are discussed. Principles for substantive investigation of growth mixture model results are presented and illustrated by an example of high scho...

This paper analyzes the conceptual framework of three statistical methods, multiple regression, path analysis, and structural equation models. When establishing research model of the statistical modeling of complex social phenomenon, it is important to know the strengths and limitations of three statistical models. This study explored the character, strength, and limitation of each modeling and...

The Statistical Knowledge Network (SKN) is envisioned as a consortium of individuals and organizations supported by technologies that enable them to share and use statistical expertise and information (Marchionini et al., 2003). The SKN would provide integrated access to statistical information from a multitude of sources and enable use of that information through statistical literacy tools, ap...

Prof. Akaike made significant contributions in various fields of statistical science, in particular, in time series analysis in frequency domain and time domain, information criterion and Bayes modeling. In this article, his research contributions are described in order of launching period, frequency time domain analysis, time domain time series modeling, AIC and statistical modeling, and Bayes...
