conditional effect in moderated mediation bootstrap command

[Manuel Hess]

Hello,

I am trying to test the conditional indirect effect in a mediated moderation model using bootstrapping. I have a multilevel model and this is the code i am using:

capture program drop bootm
program bootm, rclass
  mixed stdROA X M MW
  return scalar cielw = (-0.241*(_b[stdROA:M] + (0)*_b[stdROA:M#W] ))
  return scalar ciemn = (-0.241*(_b[stdROA:M] + (0.5)*_b[stdROA:M#W] ))
  return scalar ciehi = (-0.241*(_b[stdROA:M] + (2)*_b[stdROA:M#W] ))
end

bootstrap r(cielw) r(ciemn) r(ciehi), reps(5000)

Bootstrap does not execute and says "r(cielw) command not found".

What am i missing?

Thank you!

Thank you. I solved it by consulting this post, which described a problem I also experienced.
