The two models fitted are: (a) Φ⁻¹(p_ij) = η+u_i+v_j and (b) Φ⁻¹(p_ij) = η+βx_i+ u_i+v_j+z₂v_1j; x_i is an indicator variable for ith subject’s age (1 for subjects less than or equal to 60 years of age, 0 for subjects greater than 60 years of age). The term z₂ = 0 for an inexperienced rater, and 1 for an experienced rater. Parameter estimates are presented with standard errors in parentheses.
