Cox proportional hazards models were specified to calculate adjusted hazard ratios (HRs) for each ethnic minority group versus the reference category (whites).
We also specified how to adjust parameters (e.g., sampling rate) according to the unique characteristics of the window functions, to satisfy various application scenarios.
Hypotheses are tested using an analysis of covariance model to account for the variance removed by normalizing the measurements and to adjust for specified sources of variation (Parrish and Delongchamp, 2006).
The difference between matched and unmatched models in the odds of preterm birth and low birth weight suggests that the associations of increased risk at short intervals reported in the literature may be an artefact of unmeasured or inadequately specified confounders, despite careful attempts to adjust models.
For example, we were able to create a consistent as possible definition of LTPA and to specify which potential confounding variables to adjust for in every cohort, thus allowing us to obtain uniform estimates from each cohort.
We specified a first-order autoregressive correlation structure to adjust for within-individual autocorrelation.
The ethical theory subsequently selected had an influence on the further qualitative data gathering, while, at the same time, the empirical data collected were used to specify and adjust the ethical theory with respect to the particular context.
In these four domains, the formal and cognitive norms relevant to all kinds of scientific research were specified and adjusted to the particular field of EE research (" primary research question, theoretical framework & methods" and " relevance").
One usual approach to adjust for overdispersion is to specify a dispersion parameter ϕ for estimation [ 15].
A design procedure is developed to specify and adjust significant parameters for GA, TS, SA, EMA and VNS.
