"Splet23. feb. 2016 · The log-likelihood is simply the log of the likelihood. If a likelihood is less than 1, the log-likelihood is negative, but this can arise from noisy data, sparse data, small sample sizes, among a host of other causes. We cannot objectively say anything based on a single likelihood or log-likelihood, it is strictly relative. " - The log likelihood is parallel to
