The main advantages of the Cox model are: its suitability for multivariate analysis, no need for any specific assumptions regarding survival probability distribution in the base population, and the ability to handle time-dependent variables.
In this study, we assess imputation models for unbiasedness, under specific assumptions [condition (i ], but we did not test imputation models for their ability to preserve variability in the data [condition (ii)] or to correctly reflect among-impute variability [condition (iii)].
Design premises for this process, specific assumptions used in modeling, and resultant cost calculations are presented (see Section 3.1, Tables 1, 2, 3, and 4, and Figures 1, 2, and 3).
Design premises for this process, specific assumptions used in modeling, and the resultant cost calculations are presented (see Section 3.2, Tables 5 and 6, and Figures 4 and 5).
We study specific assumptions for u and v in two genetic models and one cultural model.
For general systems without any specific assumptions, multimeric regulation was assumed to be essential to obtain bistable behaviour [22], [23].
The plots similar to Figure 29C can be constructed for any particular example with specific assumptions about the terms A, B, C, and D in eq 25.
Many existing methods for group-wise tests require specific assumptions about the direction of individual SNP effects and/or perform poorly in the presence of interactions.
The values are averages of unit costs for the country, based on specific assumptions regarding the organisation of health services and operational capacity.
Although such models successfully simulate many phenomena associated with angiogenesis, a problem is that model input and model output are not always strictly separated: In addition to rules for tip cell motility, these models include explicit, descriptive rules for tip branching, anastomosis, and specific assumptions to prescribe the length of the branches and sometimes branching angles.
