Abstract
The main objective of this paper is to investigate the structure of survey response data on nuclear power generation. Previous studies have shown about the relationships between the responses at the individual level and at the aggregate level in some panel surveys. Some studies have reported about the stability of marginal distribution in spite of response fluctuations at the individual level. I focus on the stability of marginal distribution of response data in a panel survey where an accident of nuclear plant happened between the first wave and the second wave. Among others, I analyzed the stability of marginal response by classifying the changes of individual responses into two factors: individual fluctuation and substantial changes. I confirmed the stability of marginal response distributions of simple tabulations as well as the response structure represented in Hayashi's Quantification Method III, in spite of individual response fluctuations.
