A RDBESDataObject converted from package SDAResources dataset coots

Source: R/data.R

This data set is derived from the data(coots). The design is 2-stage cluster sampling with clusters of unequal sizes and Npsu not known. Clusters are clutches of eggs (nests) with at least 2 eggs. In each cluster, the volume of two eggs is measured. Clusters (psu) are unequal sized. In each cluster, 2 eggs are selected (ssus) and measured. The total number of psus is not known (a drawback in this example). It is assumed very large (fpc negligible). The target variable is volume (others are available).

Pckg_SDAResources_coots_H1

Format

A list containing entries required for H1 RDBES data:

DE

the Design data table. Contains 1 DE row with DEstratumName == "Pckg_SDAResources_coots_H1"

SD

the Sampling Details data table. Contains 1 child SD row

VS

the Vessel Selection data table. Contains 368 child rows (the 368 eggs/psus observed), each associated to its cluster (clutch), VSnumberTotalClusters is not known, VSnumberTotal is csize

FT

the Fishing Trip data table. Just 1:1 links to the final data (in SA)

FO

the Fishing Operation data table. Just 1:1 links to the final data (in SA)

SS

the Species Selection data table. Just 1:1 links to the final data (in SA)

SA

the Sample data table. Each volume is a SAsampleWeightMeasured. ATT volumes are *100000000 to meet type requirement (integer)

FM

the Frequency Measure data table
