Stan 2.1.0リリース

Stan 2.1.0がリリースされました。2.0.0および2.0.1には事後分布にバイアスがかかるバグがあったということで、2.1.0へアップデートすべきとのことです。

Major Bug in 2.0.0, 2.0.1
------------------------------
Stan 2.0.0 and Stan 2.0.1 introduced a bug in the implementation
of the NUTS criterion that led to poor tail exploration and
thus biased the posterior uncertainty downward.  There was no
bug in NUTS in Stan 1.3 or earlier, and 2.1 has been extensively tested
and tests put in place so this problem will not recur.

If you are using Stan 2.0.0 or 2.0.1, you should switch to 2.1.0 as
soon as possible and rerun any models you care about.
