WebApr 13, 2024 · The IPW method focuses specifically on whether smoking is positively/negatively related with area-level deprivation. Results indicate that those in the most deprived areas are significantly more likely to smoke than those in less deprived areas. In sum we can say that those from lower socioeconomic groups are more likely to smoke. WebIPWestimators use a two-step approach to estimating treatment effects: 1. They estimate the parameters of the treatment model and compute the estimated inverse- probability …
