A Note on Testing the Shoulder Condition in Line Transect Sampling
نویسنده
چکیده
We propose a new method to examine the shoulder condition of the detection function in line transect sampling. This is an improvement on the method suggested in Mack (1998). We show that our method has a lower rejection rate (Type I error) when the data are in fact from a population satisfying the shoulder condition. It is also shown that our method is much more sensitive than Mack’s method to the departures from the shoulder condition, therefore has a higher power.

Line transect sampling from a curving path.
Cutting straight line transects through dense forest is time consuming and expensive when large areas need to be surveyed for rare or highly clustered species. We argue that existing paths or game trails may be suitable as transects for line transect sampling even though they will not, in general, run straight. Formulas and software currently used to estimate local density using perpendicular d...

متن کاملThe Effect of Different Marginal Designs on the Fracture Resistance of Monolithic Zirconia Crowns
Abstract Background and Aim: One of the major problems of all ceramic restorations is their probable fracture against the occlusal force. The aim of the present in vitro study is to compare the effect of three marginal designs (shoulder, sloped shoulder, chamfer) on the fracture resistance of monolithic zirconia crowns. Materials and methods: In this in vitro study, three PEEK dies with cham...
متن کاملPredicting and correcting bias caused by measurement error in line transect sampling using multiplicative error models.
Line transect sampling is one of the most widely used methods for animal abundance assessment. Standard estimation methods assume certain detection on the transect, no animal movement, and no measurement errors. Failure of the assumptions can cause substantial bias. In this work, the effect of error measurement on line transect estimators is investigated. Based on considerations of the process ...
متن کاملThe Effect of Animal Movement on Line Transect Estimates of Abundance
Line transect sampling is a distance sampling method for estimating the abundance of wild animal populations. One key assumption of this method is that all animals are detected at their initial location. Animal movement independent of the transect and observer can thus cause substantial bias. We present an analytic expression for this bias when detection within the transect is certain (strip tr...
