This paper introduces a test for the comparison of multiple misspecifed conditional interval models, for the case of dependent observations. Model accuracy is measured using a distributional analog of mean square error, in which the approximation error associated with a given model, say model i, for a given interval, is measured by the expected squared difference between the conditional confidence interval under model i and the "true" one. When comparing more than two models, a "benchmark"

Valid asymptotic critical values are obtained via a version of the block bootstrap which properly captures the effect of parameter estimation error. The results of a small Monte Carlo experiment indicate that the test does not have unreasonable finite sample properties, given small samples of 60 and 120 observations, although the results do suggest that larger samples should likely be used in empirical applications of the test. JEL classification: C22, C52.
