Plot method for class IdtOutl in Package ‘MAINT.Data’
Description
Plots robust Mahalanobis distances and outlier cut-offs for an object describing potential outliers in a interval-valued data set
Usage
## 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’. |
