The aim of this paper is to give a bivariate asymptotic expansion of the coefficient \(y_{n k}=\left[x^{n}\right] y(x)^{k}\), where \(y(x)=\sum y_{n} x^{n}\) has a power series expansion with non-negative coefficients \(y_{n} \geqslant 0\). Such expansions are known for \(k / n \in[a, b]\) with \(a>
