Accommodating availability bias on line transect surveys using hidden Markov models.
MetadataShow full item record
Maximum likelihood methods are developed which accommodate intermittent animal availability of animals on line transect surveys. Existing 'availability bias' correction methods are shown to be inadequate in general. The new method is applied to an aerial survey of whales, using a hidden Markov model to characterise the availability process.
