##### Methods for Functions moving from and to reference parameter in Package RobExtremes'

In optIC a gain in accuracy can be obtained when computing the optimally-robust ICs at a reference parameter of the model (instead of an arbtirary one). To this end, moveL2Fam2RefParam moved the model to the reference parameter and moveICBackFromRefParam moves the obtained optimal IC back to the original parameter.

classes
##### Usage
moveL2Fam2RefParam(L2Fam, ...)
moveICBackFromRefParam(IC, L2Fam,...)
##### Arguments
L2Fam

object of class L2ParamFamily

IC

IC of class HampIC

further arguments to be passed to particular methods

##### Details

moveL2Fam2RefParam and moveICBackFromRefParam are used internally in functions robest and roptest to compute the optimally robust influence function according to the arguments given to them.

##### Value

moveL2Fam2RefParam

the L2 Family transformed to reference parameter.

moveICBackFromRefParam

the backtransformed IC.

##### Methods

moveL2Fam2RefParam

signature(L2Fam = "L2ScaleShapeUnion"): moves L2Fam to scale 1 (and, if existing location to 0).

moveICBackFromRefParam

signature(IC = "IC", L2Fam = "L2ScaleShapeUnion"): moves IC in IC back to original location and scale in L2Fam (and in addition changes Lagrange multipliers accordingly), rescaling risk where necessary.

moveICBackFromRefParam

signature(IC = "IC", L2Fam = "L2LocScaleShapeUnion"): moves IC in IC back to original location and scale in L2Fam (and in addition changes Lagrange multipliers accordingly), rescaling risk where necessary.
