Explain test data used in fitting test

[jacobq]

The test suite contains a set of points to fit without indicating where those numbers came from. Plotting them in Excel suggests that the 3rd value (y = 21.119) may be a typo (instead of y = 2.119).

The value added by a test suite is only as good as the tests are meaningful. Does anyone know where these data came from? Were they measured from some physical process? Were they generated by a mathematical model of some kind? etc.

y: [7.807, -3.74, 21.119, 2.382, 4.269, 41.57, 73.401, 98.535, 97.059, 92.147]

Oops, I just noticed that the data referenced here actually isn't the bennet5 data but rather the data used for sigmoid fitting. In any case, I think it deserves some clarification.
