Summarizes information from kernel classification methods.

Summary function for classif.knn or classif.kernel.

Usage

# S3 method for class 'classif'
summary(object, ...)

# S3 method for class 'classif'
print(x, digits = max(3, getOption("digits") - 3), ...)

Arguments

object

Estimated by kernel classification.

...

Further arguments passed to or from other methods.

x

Estimated by kernel classification.

digits

how many significant digits are to be used for numeric and complex x.

Value

Shows:

• -Probability of correct classification by group prob.classification.

• -Confusion matrix between the theoretical groups and estimated groups.

• -Highest probability of correct classification max.prob.

If the object is returned from the function classif.knn

• -Vector of probability of correct classification by number of neighbors knn.

• -Optimal number of neighbors: knn.opt.

If the object is returned from the function: classif.kernel

• -Vector of probability of correct classification by banwidth h.

• -Functional measure of closeness (optimal distance, h.opt).
