This library implements density surface modelling of line
transect data, based on the methods of Hedley et al. (2004). Some
recent developments in the literature have also be incorporated.
Outputs are point and interval estimates of population abundance
and density.
Please note that this version of dsm WILL NOT work with the Windows
package DISTANCE. For a version that works with DISTANCE, please go

Density Surface Modelling of Distance Sampling Data
Density surface modelling of line transect data. A Generalized
Additive Model-based approach is used to calculate spatially-explicit estimates
of animal abundance from distance sampling (also presence/absence and strip
transect) data. Several utility functions are provided for model checking,
plotting and variance estimation.

This library implements density surface modelling of line
transect data, based on the methods of Hedley et al. (2004). Some
recent developments in the literature have also be incorporated.
Outputs are point and interval estimates of population abundance
and density.
Please note that this version of dsm WILL NOT work with the Windows
package DISTANCE earlier than version 6.2. For a version that works with
DISTANCE 6.1, please go to:
