# ESR data, Example 1.7 in D. Collett, Modelling Binary Data, Chapman & 
# Hall, 1991 
#   
# Data on 32 patients from Institute of Medical Research, Kuala
# Lumpur, Malaysia, correlating ESR with 2 plasma proteins, fibrogen
# and gamma-globulin (both gm/l) response is ESR > 20 mm/h (0 is
# negative, 1 is positive) ESR (erythrocyte sedimentation rate) is the
# rate at which red blood cells (erythrocytes) settle out of
# suspension in blood plasma.
#   
# variables = id, fibrogen (fig), gamma-globulin (glob), resp (esr > 20)
