A number of approaches exist to pinpoint causal relationships in information science. Propensity-Rating Matching (PSM) is likely one of the older ones, having emerged round 40 years in the past. Different strategies like Structural Equation Modeling arose on the identical time. Approaches like Instrumental Variables arose a number of many years earlier than. Causal statistics remains to be a really lively area, with many new strategies being developed.
A key benefit of PSM is that it permits researchers to work with real-world information. Particularly, it…
