Did Shakespeare write a newly-discovered poem?

Abstract

The consistency of the word usage in a previously unknown nine-stanza poem attributed to Shakespeare with that of the Shakespearean canon is examined using a nonparametric empirical Bayes model. We consider also poems by Jonson, Marlowe and Donne, as well as four poems definitely attributed to Shakespeare. On balance, the poem is found to fit previous Shakespearean usage reasonably well.
