Row
Name
Description
Statistics of the original property values (labor method, X-axis)
98
C-Set Orig. min.
The smallest property value in the C-Set
99
C-Set Orig. max.
The highest property value in the C-Set
100
C-Set Orig. mean.
The mean property value of the C-Set
101
C-Set Orig. sdev
The standard deviation of the property values in the C-Set
103-
106
C-Set Pred.
Statistics of the predicted property values (NIR, Y-axis). These
values should be comparable to the similar values of the original
property values.
108
C-Set RSS
C-Set residual sum of squares = RSS should be low:
Sum((Orig-Predicted property)^2) = Sum (e^2)
110
C-Set Durbin-Watson
dw=Durbin-Watson = Sum of consecutive/succesive Residual
Difference Square / Sum of Residual Square LINK:

C-Set Durbin-Watson in
range 1.5 to 2.5
Is the dw value between 1.5 and 2.5? Answer: Yes or No
113
C-Set Resid. min
Biggest negative deviation in the C-Set property values
114
C-Set Resid. max
Biggest positive deviation in the C-Set property values
117
C-Set n
Number of C-Set spectra
Result of the final calibration
121-
190
Validation for C-Set
Spectra
Name, number of spectrum, original, predicted property and the
difference (Orig-Pred); an X for "extrapolation", in case the value
is outside the calibration range; residual value and an X for
"redidual too big", in case the value is outside the allowed range;
