\description{
  A serial dilution assay to study concentration of cockroach allergen 
  in homes of asthma sufferes.
}
\usage{data(dilution)}
\format{
  The format is:
List of 4
 \$ unknowns     : num [1:8, 1:10] matrix with optical densities for unknowns in each
                                  column
 \$ standards    : num [1:16] vector of standard solution optical densities
 \$ dil.unknowns : num [1:8] dilution factor for unknowns
 \$ dil.standards: num [1:16] dilution factor for standard solution
}
\details{
  Concentration of standard was 0.64
