%description
A simple way of fitting detection functions to distance sampling data for
both line and point transects. Adjustment term selection, left and right
truncation as well as monotonicity constraints and binning are supported.
Abundance and density estimates can also be calculated (via a
Horvitz-Thompson-like estimator) if survey area information is provided.
See Miller et al. (2019) <doi:10.18637/jss.v089.i01> for more information
on methods and <https://examples.distancesampling.org/> for example
analyses.
