getRiskFctBV for a given object of S4 class asGRisk
returns a function in bias and variance to compute the asymptotic
risk.
signature(risk = "asGRisk", biastype = "ANY"):
returns an error that the respective method is not yet implemented.
signature(risk = "asMSE", biastype = "ANY"):
returns a function with arguments bias and variance
to compute the asymptotic MSE for a given ALE at a situation where it has bias bias
(including the radius!) and variance variance.
signature(risk = "asSemivar", biastype = "onesidedBias"):
returns a function with arguments bias and variance
to compute the asymptotic semivariance error, i.e. \(E[(S_n-\theta)_+^2]\)
resp. \(E[(S_n-\theta)_-^2]\), for a given ALE \(S_n\)
at a situation where it has one-sided bias bias (including the radius!)
and variance variance.
signature(risk = "asSemivar", biastype = "asymmetricBias"):
returns a function with arguments bias and variance
to compute the asymptotic semivariance error, i.e.
\(E[\nu_1 (S_n-\theta)_+^2+\nu_2(S_n-\theta)_-^2]\)
for a given ALE \(S_n\) at a situation where it has one-sided bias
bias (including the radius!) and variance variance.
