checkIC: Generic Function for Checking ICs

Description

Generic function for checking centering and Fisher consistency of ICs.

Usage

checkIC(IC, L2Fam, ...)
# S4 method for IC,missing
checkIC(IC, out = TRUE, ..., diagnostic = FALSE)
# S4 method for IC,L2ParamFamily
checkIC(IC, L2Fam, out = TRUE,..., diagnostic = FALSE)

Value

The maximum deviation from the IC properties is returned.

Arguments

IC

object of class "IC"

L2Fam

L2-differentiable family of probability measures.

out

logical: Should the values of the checks be printed out?

...

additional parameters

diagnostic

logical; if TRUE and out==TRUE, diagnostic information on the integration is printed; independent of out, if diagnostic==TRUE, this information is returned as attribute diagnostic of the return value. .

Author

Matthias Kohl

Details

The precisions of the centering and the Fisher consistency are computed.

Diagnostics on the involved integrations are available if argument diagnostic is TRUE. Then there is attribute diagnostic attached to the return value, which may be inspected and accessed through showDiagnostic and getDiagnostic.
