Details
Five sets of levels of luteinizing hormone for each of 48 time periods, taken from Diggle (1990). These are hormone levels measured on a healty woman in 10 minute intervals over a period of 8 hours. The luteinizing hormone is one of the hormones that orchestrate the menstrual cycle and hence it is important to understand its daily variation.
This is a time series. The book gives only one time series, which
correspond to V4. I don't know what are the other four series,
the book does'nt mention them. They could be block bootstrap
replicates?
