Assay Data for the Protein DNase

SUMMARY:

The DNase data frame has 176 rows and 3 columns obtained during the development of an ELISA assay for the recombinant protein DNase in rat serum.

DATA DESCRIPTION:

This data frame contains the following columns:

VALUE:

Run
a factor giving the run from which the data were obtained.
conc
the known concentration of the protein.
density
the measured optical density in the assay. Duplicate optical density measurements were obtained.

SOURCE:

These data are described in section 5.2.3 of Davidian and Giltinan (1995), "Nonlinear Models for Repeated Measurement Data", Chapman and Hall, London.

EXAMPLES:

DNase.lis <- nlsList(density ~ fpl(conc, A, B, ld50, scal), 
               data = DNase, cluster = ~ Run) 
DNase.nlme <- nlme(DNase.lis)
