  "Description": "Functions, classes and methods for time series modelling\nwith ARIMA and related models. The aim of the package is to\nprovide consistent interface for the user. For example, a\nsingle function autocorrelations() computes various kinds of\ntheoretical and sample autocorrelations. This is work in\nprogress, see the documentation and vignettes for the current\nfunctionality.  Function sarima() fits extended multiplicative\nseasonal ARIMA models with trends, exogenous variables and\narbitrary roots on the unit circle, which can be fixed or\nestimated (for the algebraic basis for this see\n<arXiv:2208.05055>, a paper on the methodology is being\nprepared).",
