Abstract: Abstract It has been long known that the degree of the polynomial of order $$n^{-k/2}$$ in Cornish–Fisher expansion is $$k+1$$ but the proof was not given. We establish a proof of the fact and generalize it to multivariate Cornish–Fisher expansion. We also establish the validity of Cornish–Fisher expansion.
