Generic S3 method for creating an initial values function

Called by bmm() to create an initfun for models that require initial values to properly start sampling

Usage

create_initfun(model, data, formula, prior = NULL, ...)

model: The bmmodel object for with an initfun should be created
data: The user supplied data.frame used to fit the model
formula: The brmsformula generated by configure_model including the family for the bmmodel to be estimated.
prior: The brmsprior the model will be fitted with. Parameters it holds constant are absent from the Stan code and get no initial value.
...: The arguments of brms::brm() besides formula, data and prior that change the Stan data or code (data2, knots, drop_unused_levels), passed on to brms::standata() and brms::stancode().

An initfun with no arguments that generates inital values suitable for the STAN parameters generated by the respective model call
