seizures: Epileptic seizures
Description
This data set consider information from a clinical trial of 59 epileptics,
reported by Thall and Vail (1990). For each patient, the number of epileptic
seizures was recorded during a baseline period of eight weeks. Patients were
then randomized to treatment with the anti-epileptic drug progabide, or to
aplacebo in addition to standard chemotherapy. The number of seizures was then
recorded in four consecutive two-weeks intervals.source
