find_approximation_name(method, control)
the method used to approximate the likelihood. The options
are "Laplace"
, "AGQ"
(the adaptive Gaussian quadrature approximation,
from lme4
), "SR"
(the sequential reduction approximation)
and "IS"
(an importance sampling approximation).
a list of extra parameters controlling the approximation to the likelihood. See 'Details' for more information.
