✔ = performance is satisfactory ✘ = performance is not available, failed or is not satisfactory † = Analysis proceeds, but extreme items or persons are omitted or ignored ‡ = Analysis fails. Extreme items must be removed from data frame. CMLE = Conditional Maximum Likelihood Estimation; JMLE = Joint MLE; MMLE = Marginal MLE; PMLE = Pairwise MLE; LLA = Log-Linear Association; VA = Variational Approximation
