Function compare is a generic function used to assess the quality of
the model-based estimates by comparing them with the direct estimates.
Method compare.fh assesses the quality of the model-based estimates
of the Fay-Herriot model by comparing them with the direct estimates based on
a goodness-of-fit test proposed by Brown et al. (2001) and by computing
the correlation between the regression-synthetic part of the Fay-Herriot model
and the direct estimates.
compare(object, ...)# S3 method for fh
compare(object, ...)
an object of type "fh".
further arguments passed to or from other methods.
The return of compare depends on the class of its argument. The
documentation of particular methods gives detailed information about the
return of that method.
For the method for class "fh", the null hypothesis, the value W of the test statistic, the degrees of freedom and the p value of the Brown test; and the correlation coefficient of the synthetic part and the direct estimator (Chandra et al. 2015) are returned.
