%description
Functions to predict one multi-way array (i.e., a tensor) from another
multi-way array, using a low-rank CANDECOMP/PARAFAC (CP) factorization and
a ridge (L_2) penalty [Lock, EF (2018)
<doi:10.1080/10618600.2017.1401544>].  Also includes functions to sample
from the Bayesian posterior of a tensor-on-tensor model.
