Making health continuous: implications of different methods on the measurement of inequality
研究将健康从分类变量转为连续变量的不同方法（如区间回归、有序probit）对健康不平等指数的影响，发现集中指数有差异，但收入相关健康流动性指数及其分解高度相似。
In most national surveys, health is measured as a categorical variable. However, in order to be able to calculate socio-economic inequalities in health, a continuous variable is needed. The recently developed interval regression approach was shown to outperform to other approaches like ordered probit. In this research we investigate the impact of using different sets of external data to estimate health inequalities: the EQ-index and the Canadian HUI. We found that the concentration index differs, but the income-related health mobility index and its decomposition are highly similar.
