Then we shall apply the same techniques to NHEFS data set discussed in Miguel Hernan and Robins' _Causal Inference: What if_ [book](https://www.hsph.harvard.edu/miguel-hernan/causal-inference-book/). This data set measures the effect of quitting smoking between the period of 1971 and 1982.

This score is typically calculated by fitting a predictive logit model on all an individual's observed attributes predicting whether or not the those attributes drive the indivdual towards the treatment status.

-                "The reason we want this propensity score is because with observed data we often have a kind of imbalance in our covariate profiles across treatment groups. Meaning our data might be unrepresentative in some crucial aspect. This prevents us cleanly reading off treatment effects by looking at simple group differences. These \"imbalances\" can be driven by selection effects into the treatment status so that if we want to estimate the average treatment effect in the population as a whole we need to be wary that our sample might not give us generalisable insight into the treatment differences. Using propensity scores as a measure of the prevalance to adopt the treatment status in the population, we can cleverly weight the observed data to privilege observations of \"rare\" occurence in each group. For example, if smoking is the treatment status and regular running is generally not common among the group of smokers, then on the occasion we see a smoker marathon runner we should heavily weight their outcome measure to overcome their low prevalence in the treated group but real presence in the unmeasured population. Inverse propensity weighting tries to define weighting schemes are inversely proportional to an individual's propensity score so as to better recover an estimate which mitigates (somewhat) the risk of selection effect bias. For more details and illustration of these themes see the PyMC examples [write up](https://www.pymc.io/projects/examples/en/latest/causal_inference/bayesian_nonparametric_causal.html) on Non-Parametric Bayesian methods. {cite:p}`forde2024nonparam`\n"
