  ## S4 method for signature 'IdtOutl,missing'
plot(x, scale=c("linear","log"), RefDist=getRefDist(x), eta=geteta(x), 
  multiCmpCor=getmultiCmpCor(x), ...)

Arguments

x

An IData object of class IdtOutl describing potential interval-valued ouliters.

scale

The scale of the axis for the robust Mahalanobis distances.

RefDist

The assumed reference distributions used to find cutoffs defining the observations assumed as outliers. Alternatives are “ChiSq” and “CerioliBetaF” respectivelly for the usual Chi-squared, and the Beta and F distributions proposed by Cerioli (2010). By default uses the one selected in the creation of the object ‘x’.

eta

Nominal size of the null hypothesis that a given observation is not an outlier. By default uses the one selected in the creation of the object ‘x’.

multiCmpCor

Whether a multicomparison correction of the nominal size (eta) for the outliers tests was performed. Alternatives are: ‘never’ – ignoring the multicomparisons and testing all entities at the ‘eta’ nominal level. ‘always’ – testing all n entitites at 1.- (1.-‘eta’^(1/n)). By default uses the one selected in the creation of the object ‘x’.
