From: The new accounting for expected adjusted effect test (AEAE test) has higher positive predictive value than a zero-order significance test

Fig. 2

Positive predictive value (PPV) for zero-order significance tests (Eq. 2) of the effect of X on Y while adjusting for Z (thick red line) as well as when accounting for the expected adjusted effect (AEAE test, Eqs. 13, blue line) as functions of the true adjusted effect, separately for three different prior probabilities (different markers), four degrees of reliability in the measurement of Z (columns) and four degrees of reliability in the measurement of X/Y (rows). The sample size was fixed at 500 and the degree of confounding at 0.5 in these simulations
