This is the Dataplot data file DRAPS521.DAT
This is the data set from exercise I on page 521 of
Draper and Smith "Applied Regression Analysis: 2nd Edition".
This is the data used in the ODRPACK manual as a sample. We
have included it here to calibrate the Dataplot implementation
of the ODRPACK package. Data are from a simulated planned experiment.
The proposed model is:
Y = EXP{-theta1*X1*EXP[-theta2*((1/X2) - (1/620))]} + E
this other than the data is from a planned experiment.
