The values above parentheses represent odds ratio (OR) value which means the relative probability of a variable between a group and a reference group. The reference group for Age_60.25 is those age < 60.25. The reference group for Gender is those who are female, i.e., Gender = 0. The reference group for Education is those who are illiterates, i.e., Education = 1. The reference group for Self-rated health is those who are rather healthy, i.e., Self-rated = 1. The reference group for Work status is those without jobs, i.e., Work status = 0. Analysis in column (1) includes samples aged 45–75 years old, i.e., the bandwidth is 15 years. Analysis in column (2) includes samples aged 52–68 years old, i.e., the bandwidth is 8 years. Analysis in column (3) includes samples aged 53.066–66.934 years old, i.e., the bandwidth is 6.934 years, the minimum mean square error bandwidth. Analysis in column (4) includes samples aged 55–65 years old, i.e., the bandwidth is 5 years. Robust standard errors are clustered at the household level and are shown in parentheses. *p < 0.1, **p < 0.05, ***p < 0.01.
