Correlation between MUBP(ϕ) and true estimated bias, and between MUB(ϕ) and true estimated bias, versus the biserial correlation corr(U, X)=ρux, for combinations of selection mechanism (columns), μY (rows) and ϕ (shape) (results from all estimated biases (all values of βZ and βU) are all plotted together; correlations are estimated from 1000 simulated data sets for each scenario): ●, probit, MUBP(0); ▲, probit, MUBP(0.5); ■, probit, MUBP(1); ○, normal, MUBP(0); △, normal, MUBP(0.5); □, normal, MUBP(1)
