Figure 1.

Contour plots of the expected log-likelihood for the two-parameter model: (a) p₁ = 0.9, p₂ = 0.1, q₁ = 0.1, q₂ = 0.9; (b) p₁ = 0.3, p₂ = 0.7, q₁ = 0.4, q₂ = 0.6. The numbers in each plot are various levels of the expected log-likelihood. The expected log-likelihoods at the parameter combinations represented by a curve are the same.
