Statement of Retraction
We, the Authors, Editors, and Publishers of the Journal of the American Statistical Association, have retracted the following article:
P.E. Jacob, F.Lindsten, T. B. Schön. “Smoothing with Couplings of Conditional Particle Filters,” the Journal of the American Statistical Association. Published Online 6 August 2018. DOI: 10.1080/01621459.2018.1505625.
Following publication on the Latest Articles page of the journal's website, it came to light that there existed a bug in the code used to produce the numbers initially presented in the retracted version. The results themselves remain the same, and not a word will have been changed when the article publishes in final form. The final article will be the version of record in good standing.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.
