There's a whole raft load of work done in endocrine hormone pulse analysis
which may be of interest - the raw material is very noisy being the
results of radioimmune assay and sampling frequency is limited due to
practical problems like exsanguination of the subject !!
I have a package which implements the two most popular algorithms used
for that problem - cluster and pulsar in a neat pc clone piece of
shareware. Email me for details...
