| Details | The problem of false negatives, people who really have attitudes but refrain from expressing them, could seriously bias the analysis, but has largely been neglected. We treated nonresponses as nonignorably missing, in the sense that “DON'T KNOW” responses are related to the answer of the question in some partially unknown way. We proposed a method to estimate parameters in a logit model when the covariates are nonignorably missing. The method simultaneously employed two generalized linear models. We found the existence of false negatives.For PautiCrGN patients, their exitus was not non-ignorably missing at first sight, but the exitus of serious patients might have been under-reported precisely because of their conditions. |
