Radioimmunoassay Data
Description:
The 'ria' data frame has 16 rows and 2 columns.
Run of a radioimmunoassay (RIA) to estimate the concentrations of
a drug in samples of porcine serum. The experiment consists of
16 observations made at 8 different drug levels with two
replications at each level.
Usage:
data(ria)
Format:
This data frame contains the following columns:
'conc' the drug concentration (ng/ml);
'count' the observed percentage of radioactive gamma counts.
Source:
The data were obtained from

effect of variance function estimation on nonlinear calibration
inference in immunoassay data. _Biometrics_, *52*, 158-175.
