平稳过程正态性的R软件包

An R package for Normality in Stationary Processes

Izhar Asael Alonzo Matamoros, Alicia Nieto-Reyes

摘要:

正态性是分析时间序列模型中相依数据的主要假设,正态性检验在文献中得到了广泛的研究,但这些检验的实现还很有限。\textbf{nortsTest}包执行\textit{Lobato and Velasco, Epps, Psaradakis and Vavra}和\textit{random projection}的平稳过程正态性检验。此外,该软件包还提供可视化诊断功能,用于检查多个\R软件包中最常用的时间序列模型的平稳性和正态性假设。本工作的目的是展示该软件包的功能,用模拟实例展示每个测试性能,以及该软件包在时间序列分析中的模型诊断实用程序。

英文摘要:

Normality is the main assumption for analyzing dependent data in several time series models, and tests of normality have been widely studied in the literature, however, the implementations of these tests are limited. The \textbf{nortsTest} package performs the tests of \textit{Lobato and Velasco, Epps, Psaradakis and Vavra} and \textit{random projection} for normality of stationary processes. In addition, the package offers visual diagnostics for checking stationarity and normality assumptions for the most used time series models in several \R packages. The aim of this work is to show the functionality of the package, presenting each test performance with simulated examples, and the package utility for model diagnostic in time series analysis.
