Table 2.

Summary of the zero-inflation parameters and residual correlation. Table (a) gives the sample proportion of zeros and the posterior 95% intervals for the average (over subjects) zero probability $p_l+(1-p_l){\sum }_{i=1}^n\mathit{Prob}(z_{li}<0)/n$ (“posterior”) and the zero-inflation parameters p_l. Table (b) gives the 95% intervals for the elements of D^−1/2Σ^eD^−1/2, where D is k × k diagonal matrix with elements ${\mathrm{\sum }}_{ll}^e$.
