Describes how Robbin and associates sorted the 1970 Census data by Zip Code, noting a thousand variables for each of the nearly 35,600 Codes.
Finally, we further adjusted for treatment strategy by adding a three group variable to the model indicating whether the patient continued MTX or which arm he/she was randomised to.
We outline the PrefSat procedure in Algorithm 2. PrefSat encodes labelings of an AF F = (A, R ) by generating three variables per argument, i.e., the set of variables in the constructed formula are { I a, O a, U a | a ∈ A }.
A two-level full factorial design and/or a central composite design are used to optimize the operation of a distillation column by manipulating three variables: the feed flow rate, the reflux ratio and the steam flow to the reboiler.
The online tables (DS2 4) report the robustness of the final model to further adjustment/confounding by three variables: a grouping variable for those (n = 18) with subclinical depressive symptoms at study entry, and participant gender and age at entry.
Sexual behavior was defined by three variables: (a) age at sexual debut (≤ 14, 15 17 or ≥ 18 years; (b) number of sexual partners in the last 12 months (0, 1 and ≥ 2 partners); and (c) life number of partners (1, 2 3 and ≥ 4 partners).
By contrast, three variables resulted in a slightly lower p-value after PSM.
By assessing all three variables within a single sample, the present study is able to provide a more direct evaluation of the putative neurobiological mechanisms that are believed to underlie the observed volumetric decreases in HPA-axis regulatory regions in MDD.
All of the parameters β, β1 and β2 can be multiplied by a two level categorical variable for either levels of PA or time spent underground.
The soil model uncertainties are characterized by three variables representing stiffness, suction and trench.
Individuals in the model are described by three variables.
