ldb.p.correct: Probability of correct classification based on the optimal linear decision bound.

Description

Estimates the probability of correct classification under the condition in which the optimal linear decision boundary is used to categorize the samples from two multivariate normal populations with the specified parameters

Usage

ldb.p.correct(means, covs, noise = 0)

Arguments

means

a list of vectors, each specifying the means of a multivariate normal population.

covs

a matrix or a list of matrices specifying the covariance matrix of the each multivariate normal population. If a list is given and length(covs) > 2, an unweighted average of the matrices is used.

noise

an optional numeric value specifying the noise associated with the decision bound. Default to 0.
