ON USING LINEAR QUANTILE REGRESSIONS FOR CAUSAL INFERENCE
使用线性分位数回归进行因果推断
We show that the slope parameter of the linear quantile regression measures a weighted average of the local slopes of the conditional quantile function. Extending this result, we also show that the slope parameter measures a weighted average of the partial effects for a general structural function. Our results support the use of linear quantile regressions for causal inference in the presence of nonlinearity and multivariate unobserved heterogeneity. The same conclusion…
