Here ''w'' is the overall detection truncation distance and ''a'', ''b'' and ''σ'' are function-specific parameters. The half-normal and hazard-rate functions are generally considered to be most likely to represent field data that was collected under well-controlled conditionconditions. In contrast, both the uniform and negative exponential functions assume that detection probability does not drop off from the center line but remains at the same level (uniform) or increases (negative exponential); these circumstances may be indicative of problems with data collection or survey design.<ref name=buckland2001/>
