title: 'twoway: Analysis of Two-Way Tables'
version: 0.7.0
doi: 10.32614/CRAN.package.twoway
abstract: 'Carries out analyses of two-way tables with one observation per cell, together
  with graphical displays for an additive fit and a diagnostic plot for removable
  ''non-additivity'' via a power transformation of the response. It implements methods
  from Tukey''s Exploratory Data Analysis (1973) <ISBN: 978-0201076165>, including
  a 1-degree-of-freedom test for row*column ''non-additivity'', linear in the row
  and column effects.'
