Abstract:
For a one-dimensional parameter non-linear regression model
$$
x_j=g_j(\theta_0)+\varepsilon_j,\qquad j\ge 1,
$$
under some assumptions about the non-random sequence $\{g_j(\theta_0)\}_{j\ge 1}$ and the random
sequence $\{\varepsilon_j\}_{j\ge 1}$, an asymptotic expansion for the distribution of the least squares estimator of $\theta_0$ is obtained.
