R. Gatto, SADDLEPOINT APPROXIMATIONS OF MARGINAL DENSITIES AND CONFIDENCE-INTERVALS IN THE LOGISTIC-REGRESSION MEASUREMENT ERROR MODEL, Biometrics, 52(3), 1996, pp. 1096-1102
We illustrate that the saddlepoint approximation can lead to accurate
inference in the logistic regression measurement error model. The marg
inal densities of an asymptotically unbiased estimator of the regressi
on parameters are computed with a general saddlepoint approximation, a
nd bias-corrected confidence intervals for the regression parameters a
re derived.
