Class UncertaintyBounds

java.lang.Object
neqsim.process.measurementdevice.vfm.UncertaintyBounds
All Implemented Interfaces:
Serializable
public class UncertaintyBounds extends Object implements Serializable
Represents uncertainty bounds for a measured or calculated value.

This class provides confidence intervals and standard deviation for values calculated by virtual flow meters and soft sensors, enabling risk-aware decision making in production optimization.
