Dear Natalia,

  Yes, -decomp- does use the mean of each of the rhs variables from
  the regressions. Only the constant is omitted from this calculation
  and enters the final results by having its coefficient multiplied by
  1. All of the other rhs variables have their coefficients multiplied
  by the relevant means.

  The formula is implemented in -decomp- using matrices and employs
  the exact formula used by Blinder. Earlier versions of -decomp- used
  rather cryptic matrix and macro names but in the latest version
  (1.5) I have renamed all matrices and macro into more fullsome
  terms, which should make it much easier for people who want to
  inspect the code. If you open himod.ado and decomp.ado in a text
  editor you can see for yourself how the means and coefficients are

Kind regards,
