A document describing the details of the implementation of the scheme and a table of the randomized assignments can be found below. The table contains a column of participant identifiers (RID), strata (GROUP), randomized set assignements (SET), and a training set indicator (TRAINING).

A dataset with variables as follows:

  • RID -4 -4 Participant roster ID

  • GROUP -4 -4 Strata

  • SET -4 -4 Randomized set assignments

  • TRAINING -4 -4 Training set indicator
