WebMay 31, 2024 · $\begingroup$ Absolutely untrue. The authors who introduced modern conditional notation, Johnson (1924) and especially Keynes (1921) already made very subtle distinctions e.g. between observational, intentional, and even testimonial propositions, which the "do"-notation can't capture. All within standard conditional-probability notation.
In statistics, ignorability is a feature of an experiment design whereby the method of data collection (and the nature of missing data) does not depend on the missing data. A missing data mechanism such as a treatment assignment or survey sampling strategy is "ignorable" if the missing data matrix, which indicates which variables are observed or missing, is independent of the missing data conditional on the observed data.
