I'm considering submitting a paper to Annals of Applied Statistics, published by the Institute of Mathematical Statistics (IMS).
According to IMS Journals on arXiv:
Note that the IMS posts all accepted IMS journal articles on arXiv at publication.
However, the paper entries on the journal page do not link directly to the arXiv paper. Also, for at least the following publication, there is no corresponding entry on arXiv. I'm not sure what to conclude from that.
So, I was just wondering if this approach counts as open access. Also, the Wikipedia entry, Comparison of statistics journals lists Annals of Applied Statistics and other IMS journals as not open access.
