An analysis of the Schoenfeld residuals for the model with only the significant variables model showed that the assumption of proportionality of hazard for this model were met (log(Co+1), χ=8.72, p=0.350; sex, χ=3.139, p=0.077 and device, χ=1.591, p=0.207).
The results for the continuous age at migration variable (Model S1) show statistically significant effects for New Cubans only.
Additionally, Klaassen et al. [5] adopted a dynamic state variable model and showed that Pink-footed geese Anser brachyrhynchus respond to scaring practices by farmers in Norway by changing their use of stopover sites.
Using a Bayesian latent variable model, we show that the pattern of correlations among tasks is consistent with the existence of a general factor accounting for a small but significant proportion of the variance in each task (the lower bounds of 95% Bayesian credibility intervals for correlations between g and task performance all exceed 0.12).
In addition to a number of commuting and contextual variables, the model shows that the single policies main effect and multiple policies interactions are significant in affecting commuters' mode choice.
The theoretical analysis and numerical simulation of a prototype two-variable electrochemical model show that for oscillations close to a Hopf bifurcation the frequency increases with increase in rotation rate (d) following an approximate square root formula ω∝d1/2.
When including these variables and necrosis along with markers of cell adhesion and hypoxia (all with p ≤ 0.10 in univariate analysis), both necrosis and αv-integrin expression remained as independent variables (final model shown in Table 4).
While several endocrine-resistant breast cancer models are based on inappropriate activity of the EGFR signaling pathway [ 8, 22, 23], the present model shows variable activation of the EGFR downstream cascade [ 6].
Removing cohort from the variables offered to the model shows that p16 (P<0.0001) and nodal status (P=0.0016) are still significant.
The first stage results from the instrumental variables model are shown in Table 3.
