These data are referred to Duchenne muscular dystrophy (DMD), a genetically transmitted disease passed from a mother to her children. Affected male offspring may unknowingly carry the disease but female offspring with the disease die at a young age. Although carriers of DMD usually have no physical symptoms, they tend to exhibit elevated levels of serum markers. In addition the levels of these enzymes may also depend on age and season. Levels of the enzymes were measured in non carriers and in a group of carriers using standard laboratory procedures.

A data frame with 73 observations on the following 6 variables.
The first two serum markers, y3
and y4
, may be measured rather inexpensively from frozen serum. The second two, y5
and y6
, require fresh serum. An important scientific problem is whether use of the expensive second pair of readings causes an appreciable increase in the detection rate.
