We describe the Bayesian Analysis of Nuclear Dynamics (BAND) framework, a cyberinfrastructure that we are developing which will unify the treatment of nuclear models, experimental data, and associated uncertainties.

We develop a method that uses truncation-order-dependent re-expansions constrained by generic strong-coupling information to extrapolate perturbation series to the nonperturbative regime.

The strongest gains would likely come from new data on the spin observables $\Sigma_{2x}$ and $\Sigma_{2x^\prime}$ at $\omega\simeq140$ to $200$ MeV and $40^\circ$ to $120^\circ$.

Computation of these intervals requires specification of prior probability distributions ("priors") for the expansion coefficients.
