bootest {ipred} | R Documentation |
Those functions are low-level functions used by errorest
and
are normally not called by users.
bootest(y, formula, data, model, predict, nboot=25, bc632plus=FALSE, ...)
y |
the response variable, either of class factor
(classification), numeric (regression) or Surv (survival). |
formula |
a formula object. |
data |
data frame of predictors and response described in
formula . |
model |
a function implementing the predictive model to be
evaluated. The function model can either return an
object representing a fitted model or a function with
argument newdata which returns predicted values. In
this case, the predict argument to errorest is
ignored. |
predict |
a function with arguments object and newdata
only which predicts the status of the observations in newdata based
on the fitted model in object . |
nboot |
number of bootstrap replications to be used. |
bc632plus |
logical. Should the bias corrected version of misclassification error be computed? |
... |
additional arguments to model . |
