checkIF | R Documentation |
The function checkIF
checkes whether the IF properties are fulfilled,
which are Fisher consistency, centring and for positive finite radius the
MSE equation. For more details see Rieder (1994) or Kohl (2005).
checkIF(x, ...)
## S3 method for class 'optIF'
checkIF(x, rel.tol = .Machine$double.eps^0.5, ...)
## S3 method for class 'rmx'
checkIF(x, rel.tol = .Machine$double.eps^0.5, ...)
## S3 method for class 'checkIF'
print(x, digits = getOption("digits"), prefix = " ", ...)
x |
object of S3 class |
rel.tol |
relative accuracy requested; see |
digits |
minimal number of significant digits. |
prefix |
string, passed to |
... |
further arguments passed through. |
The function is inspired by the function checkIC
of the RobASt-family
of packages.
An object of class "checkIF"
is returned. It contails at least the
following arguments:
Fisher |
precision of Fisher consistency condition. |
center |
precision of centering. |
mse.eq |
precision of MSE equation. |
