Question: Derive residual df for a latent class model with q latent classes. When I = 2, for q 2 show one needs T

Derive residual df for a latent class model with q latent classes. When I = 2, for q ≥ 2 show one needs T ≥ 4 for the model to be unsaturated. Then, find the maximum value for q when T = 4, 5. For an I² table, show one needs q < I² /(2I – 1).
