+Dataset Name:  Misra1a           (Misra1a.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.
