Pilot-Plant data from Daniel and Wood (1971). The response variable corresponds to the acid content determined by titration and the explanatory variable is the organic acid content determined by extraction and weighing. This data set was analyzed also by Yale and Forsythe (1976).
A data frame with 20 observations on the following 2 variables.
Organic acid content - extraction
Acid content - titration
