摘要: Abstract Iterated GLS has a remarkable property when applied to the random effects model in its usual parameterization. The values for parameter that measures relative variance, obtained through successive iterations, form monotonic sequence. This provides convenient checks multiple maxima of likelihood function and existence local maximum satisfies non-negativity condition.
