In most cases, you may want to use generate_datasets to build the object, but
for full control, you can also create datasets directly via this function.
SBC_datasets(variables, generated, parameters = NULL)draws of "true" values of unobserved parameters or other derived variables.
An object of class draws_matrix (from the posterior package)
a list of objects that can be passed as data to the backend you plan to use.
(e.g. list of values for Stan-based backends, a data frame for SBC_backend_brms)
DEPRECATED. Use variables instead.
