calc_replicate_weights | R Documentation |
Takes the output of 'cluster_gen' to calculate the replicate weights as well as some summary statistics
calc_replicate_weights(data, method, k = 0)
data |
list of background questionnaire data (typically generated by 'cluster_gen') |
method |
replication method. Can be "Jackknife", "BRR" or "BRR Fay" |
k |
deflating weight factor (used only when 'method = "BRR Fay") |
Replicate weights can be calculated using the Jackknife for unstratified two-stage sample designs or Balanced Repeated Replication (BRR) with or without Fay's modification. According to OECD (2015), PISA uses the Fay method with a factor of 0.5. This is why 'k = .5' by default.
list with data and, if requeted, some statistics
This function is essentially a big wrapper for 'replicate_var', applying that function on each element of an output of 'cluster_gen'.
