Description Usage Arguments Value Examples
Given an imputex object, this funciton plots:
(1) The
approximate averaged quantiles of the valid part of the censored conditonal
distributions, from which the proposed vectors were 'drawn' before the
proposals were aggregated via median to become the imputed vector.
(2) The
actual imputations for each observation. The red dots are the median
proposals, which are in fact the final imputed vector.
(3) Density plots on
each proposal vector. Consider that each proposal vector is drawn from a
bootmodel-distribution, whose observations have their own parameters. So
each proposal vector is a realization of a mixed distribution. Suppose, that
the booted models are relatively similar, the density estimates on all
proposal vectors (which are displayed) should be relatively similar with
little variation.
