Function to compute the prediction accuracy from an object
"stablelearnerList" as a parallel
to the similarity values estimated by
stability in each
iteration of the stability assessment procedure.
accuracy(x, measure = "kappa", na.action = na.exclude, applyfun = NULL, cores = NULL)
an object of class
a character string (or a vector of character strings).
Name(s) of the measure(s) used to compute accuracy. Currently implemented
a function which indicates what should happen to the predictions
of the results containing
integer. The number of cores to use in multicore computations
This function can be used to compute prediction accuracy after the stability was
A matrix of size
2*B times length(
measure) containing prediction
accuracy values of the learners trained during the stability assessment procedure.
library("partykit") res <- ctree(Species ~ ., data = iris) stab <- stability(res) accuracy(stab)
