Fields

double obsValue

Observation value.

double Lambda

“Information” of the observation (=inverse of the variance)

bool time_invariant

whether the observation will lose weight (lambda) as time goes on (default false)

Methods

virtual double evaluateResidual() const

Return the residual/error of this observation.

virtual double getInformation() const

Return the inverse of the variance of this constraint.

virtual void evalJacobian(double& dr_dx) const

Returns the derivative of the residual wrt the node value.
