Dataset Name: Eckerle4 (Eckerle4.dat)
File Format: ASCII
Starting Values (lines 41 to 43)
Certified Values (lines 41 to 48)
Data (lines 61 to 95)
Procedure: Nonlinear Least Squares Regression
Description: These data are the result of a NIST study involving
circular interference transmittance. The response
variable is transmittance, and the predictor variable
is wavelength.
