Background.

Misclassification of exposure variables in epidemiologic studies may lead to biased estimation of parameters and loss of power in statistical inferences.

In this paper, the inverse matrix method, as an efficient method of the correction of odds ratio for the misclassification of a binary exposure, was generalized to nondifferential misclassification and 2×2×J tables.

Methods.

Simple estimates for predictive values when misclassification is nondifferential are presented.

Using them, we estimated the corrected log odds ratio and its variance for 2×2×J tables, using the inverse matrix method.

A two-step weighted likelihood method was also developed.

Moreover, we compared the matrix and inverse matrix methods to the maximum likelihood (MLE) method using a simulation study.

Results.

In all situations, the inverse matrix method proved to be more efficient than the matrix method.

Matrix and inverse matrix methods for nondifferential situations are more efficient than differential misclassification.

Conclusions.

Although MLE is optimal among all of the methods, it is computationally difficult and requires programming.

On the other hand, the inverse matrix method with a simple closed-form presents acceptable efficiency.
