| Summary: | This paper proposes an improved likelihood-based method to test for first-order moving average in
the disturbances of nonlinear regression models. The proposed method has a third-order distributional
accuracy which makes it particularly attractive for inference in small sample sizes models. Compared to
the commonly used first-order methods such as likelihood ratio and Wald tests which rely on large samples
and asymptotic properties of the maximum likelihood estimation, the proposed method has remarkable
accuracy. Monte Carlo simulations are provided to show how the proposed method outperforms the existing
ones. Two empirical examples including a power regression model of aggregate consumption and a
Gompertz growth model of mobile cellular usage in the US are presented to illustrate the implementation
and usefulness of the proposed method in practice. |
