Dataset
Name:

Chwirut1

Procedure: Nonlinear Least Squares Regression
Certification Method & Definitions

Data: 1 Response Variable (y)
1 Predictor Variable (x)
214 Observations
Lower Level of Difficulty
Observed Data

Model: y = f(x;beta) + e   =  (exp [-beta(1)x]) / (beta(2) + beta(3)x)  + e


These data are the result of a NIST study involving ultrasonic calibration. The response variable is ultrasonic response, and the predictor variable is metal distance.
