+File Format: ASCII
+ Starting Values (lines 41 to 43)
+ Certified Values (lines 41 to 48)
+ Data (lines 61 to 188)

+Procedure: Nonlinear Least Squares Regression
+
+Description: These data are the result of a study involving
+ the analysis of performance degradation data from
+ accelerated tests, published in IEEE Transactions
+ on Reliability. The response variable is dialectric
+ breakdown strength in kilo-volts, and the predictor
+ variables are time in weeks and temperature in degrees
+ Celcius.
