The Editors of The Journal of Symbolic Logic and the author have retracted the following article:
Rate of Convergence of Computable Predictions
The author of this paper identified several mathematical errors in the article. In particular, the proof of Theorem 4.1 uses an incorrect identity, and the proof of Proposition 4.16 relies on an inequality that does not hold under the stated assumptions.
The Editors reviewed the concerns raised by the author and agreed that given the extent of the necessary corrections, a corrigendum would not be sufficient to resolve these issues.
In view of the significance of the errors and the substantial revisions required, the Editors agreed that retraction of the original article, with subsequent resubmission of a revised version, would be the best course of action. The author hopes that most of the results can be retained in a revised version.
The author has agreed to this retraction and apologises for the errors.
