Repertory and the symptom loquacity: some results from a pilot study on likelihood ratio
Homeopathy, 2004, 93 (4), 190-192

Entries in repertory rubrics can be validated, but must still be handled carefully. Prospective research is the only acceptable way. Software to support this research must be carefully designed to export correct data.
