概要	The problem of false negatives, people who have attitudes but refrain from expressing them, could seriously bias the analysis but has largely been neglected. Using survey data including a number of DO NOT KNOW responses, this paper examined whether DO NOT KNOW respondents had underlying attitudes. We treated these nonresponses as nonignorably missing, in the sense that DO NOT KNOW responses are related to the answer to 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: the proportional odds model for the response variable Party Support and the multinomial logit model for the nonresponse. We found that DO NOT KNOW responses to the Cabinet support question depended on whether the respondents supported the Cabinet, indicating the existence of false negatives.
