Should Simpson's paradox be conflated with causal interaction?
Simpson’s Paradox should not be conflated with causalinteraction, however. What is distinctive of the paradox is not thatthe probabilistic relationship reverses upon partitioning, but ratherthat it reverses in allof the resulting subpopulations. Debate 2: Average Effects
What is the most general version of Simpson's paradox?
Finally, the most general version of Simpson’s Paradox is theAmalgamation Paradox (AMP)identified by Good andMittal (1987). This paradox occurs when the overall degree ofassociation is bigger (or smaller) than each degree of association inthe subpopulations, or mathematically,
What is Simpson's paradox for quantitative data?
Simpson's paradox for quantitative data: a positive trend ( , ) appears for two separate groups, whereas a negative trend ( ) appears when the groups are combined.
Which linear regression model illustrates Simpson's paradox for bivariate Cardinal data?
Figure 4:A linear regression model thatillustrates Simpson’s Paradox for bivariate cardinal data. Eachcluster of values corresponds to a single person (repeatedmeasurement). A similar example is presented in Figure 4, adapted from Kievit, Frankenhuis, Waldorp, and Borsboom (2013).
