Publications below by Douglas R. White, esp. 1988 and 2000, explain the method. Analyses of up to 50 binary variables result in an implicational structure or diagram of:

  • Which variables entail others (asymmetrically) at various levels of exceptions
  • Which variables are statistically equivalent at various levels of exceptions
  • Which variables are mutually exclusive with others at various levels of exceptions
  • Overall "entailment structure digraphs" are nested for each level of analysis
