  2. Results of statistical analysis using residual analysis
  3. aIn those aged below 65 years, those who were retired accounted for less than the expected value, while those who were employed comprised more than the expected value. On the other hand, among those aged 65 or older, those who were retired formed more than the expected value, while those who were employed formed less than the expected value. In the case of men, those who were unemployed comprised less than the expected value, and those who were retired or employed formed larger than the expected values. On the other hand, in the case of women, those who were unemployed formed larger than the expected value, and those who were retired or employed formed less than the expected value
  4. bIn those below 65 years, those who were living alone or spouses formed less than the expected values, while those who chose “other” comprised larger than the expected value. On the other hand, among those aged 65 or older, those who were living alone or spouses formed larger than the expected values; those who chose “other” formed less than the expected value
