ApplyBayesTheorem4Likelihoods: ApplyBayesTheorem4Likelihoods

Description

Calculates the posteriors, for given likelihoods and priors using the Bayes Theorem

Usage

ApplyBayesTheorem4Likelihoods(Likelihoods,Priors,threshold=.Machine$double.eps*1000)

Value

Posteriors

[1:n, 1:d] Numeric matrix with posterior probability according to the bayes theorem.

Arguments

Likelihoods

List of d numeric matrices, one per feature, each matrix with 1:k columns containing the distribution of class 1:k.

Priors

[1:k] Numeric vector with prior probability for each class.

threshold

(Optional: Default=0.00001).
