Second-order asymptotic efficiency of PMLE in generalized linear models

In this paper, the author discusses the second-order asymptotic efficiency of pseudo-maximum likelihood estimator of [beta] based on Yi = f(Xi, [beta]) + g(Ti) + [epsilon]i, I = 1, ..., n, where Xi, Ti, [epsilon]i are independent, (·, ·) is known, but g is unknown, [epsilon] ~ [phi](·) is known with mean 0 and variance [sigma]2.
