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.
