Notes. High = High Measurement Quality; Med = Medium Measurement Quality; Low = Low Measurement Quality; Max Prob = Maximum-Probability Assignment; Pseudo-Class = 20 Pseudo-Class Draws. The true proportions of past-year binge drinking conditional on membership in the Household & Peer Risk latent class were .67 for the large effect, .48 for the medium effect, .37 for the small effect, and .30 for the no effect conditions.
