Low CUSUM use the inverted sign (always positive) (Q793)
When using the CUSUM filter for a continuous configuration the Low CUSUM series is incorrectly displayed using positive values.
The correct way of displaying the Low CUSUM data is with a negative sign as in SIMCA and SIMCA-4000.
Fixed in SIMCA-online 13.3.
Low CUSUM is a limit in the CUSUM control chart which should always be negative. However, in the products listed above, the displayed Low CUSUM is displayed with inverted sign and thus always positive.
