\title{
Data frame of the effect of buffer compositions on DNA strand displacement
amplification. A 4-d regression data set with
with replication. This is a useful test data set for exercising function
fitting methods.
}
\description{
The \code{BD} data frame has 89 rows and 5 columns. There are 89 runs with
four buffer components (KCL, MgCl2, KP04, dnTP) systematically varied in
a space-filliing design. The response is the DNA amplification rate.
}
\format{
This data frame contains the following columns:
\describe{
\item{KCl}{
Buffer component.
}
\item{MgCl2}{
Buffer component.
}
\item{KPO4}{
Buffer component.
}
\item{dNTP}{
Buffer component, deoxyribonucleotides.
}
\item{lnya}{
Exponential amplification rate on a log scale, i.e. the actual amplification
rate.
}
}
