BD {fields} | R Documentation

## 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 `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:

KCl
  Buffer component.
MgCl2
  Buffer component.
KPO4
  Buffer component.
dNTP
  Buffer component, deoxyribonucleotides.
lnya
  Exponential amplification rate on a log scale, i.e. the actual amplification rate.
