3.18.2 Calibration Residual Limits
Description The min. and max. residual is depending on the number of primary PCs.
Use The maximum allowed residual of the calibration is valid for the application.
Method PCR / PLS / Cluster (CLU) / SIMCA
Matrices ID 55
Tip The highest residual of the C-Set is used for the residual limit calculation.
Details The allowed residual = 2 * maximum C-Set residual. 2 is the default of
residual blow up, can be edited by the user.

3.18.3 Calibration Residual Limits with Blow Up
Description The min. and max. residual is depending on the number of primary PCs.
Use The maximum allowed residual of the calibration is valid for the application.
Method PCR / PLS / Cluster (CLU) / SIMCA
Matrices ID 56
Tip The highest residual of the C-Set is used for the residual limit calculation.
Details The allowed residual = 2 * maximum C-Set residual.
2 is the default of residual blow up, can be edited by the user. Do not use
residual blow up smaller as 1!
The minimum residual = minimum C-Set residual /2. It is not used for the
application.
