Add bayesian model fitting via variational inference #21
Variational inference is supported by
Turing.vi()
and can be easily implemented using a custom_fit
function.See https://turing.ml/dev/tutorials/09-variational-inference/ for details about VI in Turing.jl
This might require an additional
EstimationType
in JuliaPsychometrics/AbstractItemResponseModels.jl since VI does return aT <: Distribution
not posterior samples or a single point estimate.
