abstract: Functions to estimate the probability to receive the observed treatment,
  based on individual characteristics. The inverse of these probabilities can be used
  as weights when estimating causal effects from observational data via marginal structural
  models. Both point treatment situations and longitudinal studies can be analysed.
  The same functions can be used to correct for informative censoring.
