A series of restricted models using the same specifications as the basic models, but with data on only those households included in the full models, yielded similar results to the basic models for all four outcomes (Supplemental Table 5).
Thus, most current approaches for duplication analysis rely on heuristics, approximation algorithms, or restricted models of duplication [ 3- 7].
This was done to compare the fit of the restricted models to the saturated model.
Additionally, age (by decade), sex, dialysis status (1 = patient on dialysis; 0 = patient not on dialysis), and the 6 significant EIGENSTRAT principal components were included as covariates in both the full and restricted models.
Effect estimates for lead exposure on differences in diastolic blood pressure in this restricted model were similar to those obtained in the full model.
The paper by Tofigh et al. (2011) studies a restricted version of the reconciliation model that ignores losses (equivalent to assigning a cost of zero for loss events under the DTL reconciliation problem) and shows that, under this restricted model, the DTL reconciliation problem on undated trees can be solved in O(mn) time.
The achievable equal rate point for DF, CF, AF, and CoF is given for the so-called restricted model, in which the nodes' channel inputs depend only on their own messages, not on past symbols.
The final restricted model constructed from the derivation cohort was then tested on the validation cohort.
If a less restricted model does not show improved fit over a more restricted one, then the more parsimonious restricted model is the appropriate one.
The restricted model provided a better fit then the exhaustive model; the health motive was proven to have indirect influence on attitude through knowledge and label use.
