Abbreviations: original BNFCS2004 the usual intake distribution obtained from the original BNFCS2004 data, simulated BNFCS2004 the usual intake distribution obtained from the simulated BNFCS2004 data, simulated “true” the usual intake distribution obtained from the simulated “true” intake data. The table also shows the residual variance (σ ²) and the division of this variance in the within (${\sigma }_{w,t}^2$)- and between (${\sigma }_{b,t}^2$)-individual variance, these variances were estimated on the transformed scale
