ReportingRate: Calculates angler reporting rate of non-reward tags.

In jasondubois/sportfish: Methods and Function for CDFW Sportfish Unit Data

Description

In mark-recapture studies, anglers are encouraged to return tags to the issuing entity. A mixture of non-reward tags and high-value reward tags typically are released to ensure returns. Not all anglers return tags (non-reporting), and the reporting rate adjusts for non-reporting.

Usage

ReportingRate(rr, rt, nr, nt)

Arguments

rr	Number of non-reward tags reported (positive integer).
rt	Number of non-reward tags released (positive integer).
nr	Number of high-reward tags reported (positive integer).
nt	Number of high-reward tags released (positive integer).

Value

List containing reporting rate and reporting rate variance.

Note

In the case of CDFW sturgeon mark-recapture, all tags released are reward tags. We assume, then, a reporting rate of 100 the highest value reward.
