Misra1a {NISTnls} | R Documentation |
The Misra1a
data frame has 14 rows and 2 columns.
This data frame contains the following columns:
These data are the result of a NIST study regarding dental research in monomolecular adsorption. The response variable is volume, and the predictor variable is pressure.
