CRAN’s New Missing Data Task View. Time-Series, Domain-Theory . Although every regression model in statistics solves an optimization problem they are not part of this view. Releases 35 tags. q is the order of the MA term. In the matrix case, each column of the matrix data is assumed to contain a single (univariate) time series. Applications of extreme value theory can be found in other task views: for financial and actuarial analysis in the Finance task view, for environmental analysis in the Environmetrics task view. This CRAN task view contains a list of packages which offer facilities for solving optimization problems. Spatial data processing The CRAN Spatial Task View gives an overview of packages to be used in R to read, visualise, and analyse spatial data. (See also the CRAN task view MachineLearning.) Infrastructure for regularly spaced time series : The class "ts" in package stats is R's standard class for regularly spaced time series (especially annual, quarterly, and monthly data). Time series models for financial econometrics (e.g., GARCH, stochastic volatility models, or stochastic differential equations, etc.) For example, R includes general tools for regular time series and forecasting (see e.g.,Pfa 2008;Hyndman and Khandakar2008) or for handling irregular time series (Zeileis and Grothendieck2005). For R implementations see the CRAN Task View: Time Series Analysis (also here). For more information on importing sequence data, see the Genetics task view; pegas may also be of use. are described in the Finance task view. This CRAN Task View contains a list of packages useful for empirical work in Finance, grouped by topic. are described in the Finance task view. The packages mentioned in other answers provide flexible interfaces to cast a broad range of time series models in state-space form and give sound implementations of the Kalman filter. Picking forty was unusually difficult. Time Series Forecasting finds a lot of applications in many branches of industry or business. I will probably submit them to CRAN after they’ve been tested by a few more people. This CRAN task view contains a list of packages related to accessibility of different databases. Details. The package offers some utilities to fit the basic structural time series model. Tools for time series analysis are widely available in R (R Core Team2014). Time series packages on R. Hyndsight. It allows to predict product demand (thus optimizing production and warehouse storage), forecast amount of money from sales (adjusting company’s expenses) or to predict future values of stock prices. 30000 . Visual puns are mine. (2 replies) Dear UseRs, the new Task View "ExperimentalDesign" (Title: Design of Experiments (DoE) & Analysis of Experimental Data) has just been uploaded to CRAN. Time series/Paleontology: Paleontological time series data can be analyzed using a likelihood-based framework for fitting and comparing models (using a model testing approach) of phyletic evolution (based on the random walk or stasis model) using paleoTS . Download R R and its packages are available to download for free at CRAN. 20000 . Every time I need to do a time-series forecasting, I use the tool that I know well: the forecast package and functions from there (most commonly ets). These are vectors or matrices with class of "ts" (and additional attributes) which represent data which has been sampled at equispaced points in time. The problem is that I find it to be a pain in the ass to work with ts and xts objects and go out of my way to construct a model. Financial Time Series Objects. You can also use the CRAN Task Views, where … There is now an official CRAN Task View for Time Series. This week I have finished preliminary versions of two new R packages for time series analysis. Multivariate, Time-Series . Anomaly detection problems have many different facets and the detection techniques can be highly influenced by the way we define anomalies, the type of input data to the algorithm, the expected output, etc. Two hundred ninety-two new packages made it to CRAN in November. The package stsm is now available on CRAN. This will replace my earlier list of time series packages for R, and provide a more visible and useful entry point for people wanting to use R for time series analysis.
