exp_implicit_missing_visits

Internal function called by check_df_visit().

Monitoring of Adverse Event (AE) reporting in clinical trials is
important for patient safety. Sites that are under-reporting AEs can be detected
using Bootstrap-based simulations that simulate overall AE reporting. Based on the
simulation an AE under-reporting probability is assigned to each site in a
given trial (Koneswarakantha 2021 <doi:10.1007/s40264-020-01011-5>).
