NIST/ITL StRD Dataset Name: Misra1b (Misra1b.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. Reference: Misra, D., NIST (1978). Dental Research Monomolecular Adsorption Study.
