normalizelogweights {varbvs}

Compute normalized probabilities.

Description

Compute normalized probabilities from unnormalized log-probabilities.

Usage

  normalizelogweights(logw)

Arguments

logw

Vector of unnormalized log-probabilities.

Details

Guards against underflow or overflow by adjusting the log-probabilities so that the largest probability is 1.

Value

Normalized probabilities such that the sum is equal to 1.
