.check_estimability
calculates the matrix of second-derivatives of the marginal likelihood
w.r.t. fixed effects, to see if any linear combinations are not estimable (i.e. cannot be
uniquely estimated conditional upon model structure and available data, e.g., resulting
in a likelihood ridge and singular, non-invertable Hessian matrix)
