Our results suggest that that a cubic model involving age is appropriate for all of the three measures of respiratory function that we have analysed.
Model building began with terms representing the main effects, and included interaction terms involving age, BMI, and menopausal status as suggested by visual inspection of the stratified analyses.
These opposite effects might reflect differences between the two distantly related yeasts and/or between the two distinct chronological aging models involving glucose depletion in budding yeast and long-term quiescence on nitrogen depletion in fission yeast.
Subsequently, interaction models involving the product of dioxin with age, body fat, and group were considered; many of these indicated significant interactions, motivating stratification.
The transactional model was tested in three-wave longitudinal cross-lagged models involving 117 children (78.5% boys) aged 4 at the beginning of the study and three caregivers, i.e. their mother, father and teacher.
The model was simplified to remove age group as a factor given the absence of age-group differences (or interactions involving age-group contrasts) in strength-normalized measures of anterior tongue-palate pressure amplitudes in question (2).
Attention is focused on composites involving ageing constituents.
Although single-cohort samples have traditionally been thought of as providing information primarily about Nb [based on a model involving semelparous, age-structured species (Waples 2005)], Equation 5 and Figure 2 indicate that both Nb and Ne strongly influence effective size estimates in iteroparous species.
The differential delay equations have useful applications in various fields such as age-structured population growth, control theory, and any models involving responses with nonzero delays [1 5].
