- Abstract
A discrete measurement error (ME) model for radial distance and angle to detected objects in line transect surveys is considered. This approach directly quantifies the effect of ME on the estimated effective strip half‐width. The method is applied to data from experiment and sighting data collected over the period 2008–2013 in North Atlantic both under the assumption of multiplicative and additive ME. The results indicate that the abundance estimates obtained by taking ME into account are consistently larger than the abundance estimates without ME correction. Furthermore, some insights into the effect of ME are provided by a theoretical analysis.
