A model is given for line transect sampling for the purpose of estimating animal population density which makes no assumption about the value of the detection probability along the transect or about ...

subdivide an area into transects and perform a scientific study. use a magnetic compass to determine the N/S and E/W directions in the transect. grid the transect and transcribe the biotic and abiotic ...

The estimation of the abundance of animal populations with the line-transect sampling method requires that a sighting model be postulated to represent the decreased probability of a sighting as its ...
