        CHANGES IN VERSION 0.6-18 (2017-03-16)
  • added a 'vignette'

          CHANGES IN VERSION 0.6-16 (2014-05-17)
  • corrected formatting in the documentation

          CHANGES IN VERSION 0.6-14 (2014-04-22)
  • 'micEconAids' no longer depends on packages 'miscTools' and 'systemfit' but imports these packages

          CHANGES IN VERSION 0.6-12 (2012-12-26)
  • corrected dependencies: replaced "R (>= 2.4.0)" and "stats (>= 2.15.0)" (where the latter implies "R (>= 2.15.0)") by "R (>= 2.14.0)" and "stats" (without version number), because R/stats 2.14.0 is sufficient

          CHANGES IN VERSION 0.6-8 (2012-06-02)
  • added nobs() method for objects of class "aidsElas"

          CHANGES IN VERSION 0.6-6 (2011-11-12)
  • fixed partial argument matching in aidsElas()

          CHANGES IN VERSION 0.6-4
  • added a note in the "details" section of the documentation of aidsElas that explains how the adjusted alpha_i coefficients can be calculated if the model was estimated with demand shifters

          CHANGES IN VERSION 0.6-2
  • aidsElas() now stops and returns an error message if the model includes demand shifters, because it (currently) cannot calculate elasticities of models with demand shifters (it does not adjust the alpha coefficients); the documentation of aidsElas() now mentions this limitation and gives a hint how the user can use aidsElas() to calculate elasticities for models with demand shifters anyway (the author of micEconAids is grateful to Jens Hainmueller who reported this bug)
