In conclusion, time-series analysis is a new tool that can help us make sense of antimicrobial use and resistance surveillance data,an area where modeling has proven difficult. Future developments must include confirmation of the usefulness of this method in other hospitals and in other countries....
书中一句很有启发性的话: correlation is an essential feature of time series analysis 2011-07-08 17:57:31 回应 1.4 1.4.独立性的度量:自回归和交叉自回归(1)边际分布对时间序列分析更为有效(这个是对传统的统计学重视研究随机变量分布而言的)(2)要掌握的统计量:均值函数(注意是利用边际分布函数求得),自...

We will also provide additional code and other information of interest on the text’s website. Most of the material that would be given in an introductory course on time series analysis has associated R code. Although examples are given in R, the material is not R-dependent. In courses we...
It: The irregular component (or "noise") at timetrepresents random and irregular influences. It is the remainder of the time series after removing other components. Additive decomposition:Additive decomposition implies that time-series data is a function of the sum of its components. This can be...

Temporal behavior is an essential aspect of all biological systems. Time series have been previously represented as networks. Such representations must address two fundamental problems on how to: (1) Create appropriate networks to reflect the characteristics of biological time series. (2) Detect charac...
