EstimatesWBPHS: Standard ratio estimator for WBPHS survey data

In USFWS/AKaerial: Analysis of Alaska Region Aerial Survey Data

Standard ratio estimator for WBPHS survey data

Description

EstimatesWBPHS will combine spatially-referenced observations with design transects and strata to create an index estimate

Usage

EstimatesWBPHS(data, flight)

Arguments

data	The ReadWBPHS list object to be analyzed
flight	Flight summary from SummaryWBPHS

Details

EstimatesWBPHS is the primary function in AKaerial for producing index estimates for the WBPHS survey. It will take an object from ReadWBPHS and adjust counts, summarize spatial information, and calculate indices and their associated standard errors. Also retained are estimates of densities of bird by strata and on each transect.

Value

List object with 2 elements:

1. output.table Observer-specific estimates for the species indicated in the sppntable estimates column

2. expanded.table Deeper level count information by transect, strata, species, and observer
