In Distance: Distance Sampling Detection Function and Abundance Estimation

Simulated line transect survey data with covariates

Description

Simulated line transect survey. Only eight line transects, detection function is half-normal.

Format

A data.frame with 60 rows and 9 variables

• Region.Label strata names (single stratum)

• Area size of study area (mi^2)

• Sample.Label transect ID

• Effort transect length (mi)

• object object ID

• distance perpendicular distance (km)

• MSTDO time since medication taken by observer (min)

• Hour time of day of sighting (hour)

• Study.Area name of study area

Note

Hour is covariate that has no effect on detection function, while MSTDO does affect the detection function. Examine the ability of model selection to choose the correct model.
