Dataset Name:  Misra1d           (Misra1d.dat)

File Format:   ASCII

               Starting Values   (lines 41 to 42)

               Certified Values  (lines 41 to 47)

               Data              (lines 61 to 74)

Procedure:     Nonlinear Least Squares Regression

Description:   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.
