dfms 0.2.2

  • Replace Armadillo inv_sympd() by Armadillo inv() in C++ Kalman Filter to improve numerical robustness at a minor performance cost.

dfms 0.2.1

  • Fixed print bug in summary.dfm: print method showed that model had AR(1) errors even though idio.ar1 = FALSE by default.

dfms 0.2.0

  • Added argument idio.ar1 = TRUE allowing estimation of approximate DFM's with AR(1) observation errors.

  • Added a small theoretical vignette entitled 'Dynamic Factor Models: A Very Short Introduction'. This vignette lays a foundation for the present and future functionality of dfms. I plan to implement all features described in this vignette until summer 2023.

dfms 0.1.5

  • Added argument na.keep = TRUE to fitted.dfm. Setting na.keep = FALSE allows interpolation of data based on the DFM. Thanks @apoorvalal (#45).

dfms 0.1.4

  • Fixed minor bug in summary.dfm occurring if only one factor was estimated (basically an issue with dropping matrix dimensions which lead the factor summary statistics to be displayed without names).

dfms 0.1.3

  • Implemented some minor CRAN comments, no changes to functionality.

dfms 0.1.2

  • New default em.method = "auto", which uses "BM" if the data has any missing values and "DGR" otherwise.

  • Added vignette providing a walkthrough of the main features.

dfms 0.1.1

  • Renamed package from DFM to dfms. Lowercase names are preferred by rOpenSci, and this also helps distinguish the package name from the main function DFM(). The new name was inspired by the vars package.
