prepareInputToAllocation2 {R2BEAT}

Input dataframes for R2BEAT two-stages sample design when both sampling frame and a previous round of the survey are available

Description

In case of scenario 2 (at least one previous round of the survey available), prepares the following input dataframes for R2BEAT two-stages sample design starting from the sampling frame: 1. strata 2. deff 3. effst 4. rho 5. PSU_file 6. des_file

Usage

prepareInputToAllocation2 ( 
  samp_frame,
  RGdes, 
  RGcal, 
  id_PSU, 
  id_SSU, 
  strata_var, 
  target_vars, 
  deff_var, 
  domain_var,
  delta,
  minimum) 

Arguments

samp_frame

The dataframe containing sampling units in the reference population.

RGdes

The 'design' ReGenesees object.

RGcal

The 'calibration' ReGenesees object.

id_PSU

variables used as identifiers in sampling frame.

id_SSU

variables used as identifiers in sampling frame.

strata_var

stratification variable used in sampling frame.

target_vars

target variables.

deff_var

stratification variable to be used when calculating deff.

domain_var

the variable used to identify the domain of interest.

delta

average number of analysis units per sampling unit.

minimum

minimum number of SSU to be selected from a PSU.

Value

A list containing: (1) strata, (2) deff, (3) effst, (4) rho, (5) PSU_file, (6) des_file
