Nevertheless, when combined, the variables contribute to a plausible and transparent classification.
We combined the variables described above into a multivariate model, and this analysis confirmed the indications of the independent tests.
For correlated variables that measured similar features, we either combined the variables or selected the most important variable for further analysis.
Similarly, we combined the variables for current use of typical and atypical antipsychotic drugs into one variable and equine and non-equine hormone replacement therapy into another variable.
We combined the variables pre-existing diabetes and gestational diabetes to describe 'diabetes in pregnancy', because of the small numbers of pre-existing diabetes cases (n = 53).
The following variables were significantly associated with the size of the ulcer on day 21: size of ulcer on day 1 and the variable that combined the variables treatment and body condition (Table 3).
Meanwhile, when we combined the variables of SNAP, gestational age, apnea of prematurity, PDA, and surfactant use in the final model, specificity increased to 90%, and positive likelihood ratio increased to 7.4.
Initially, a Primary Health Care Index (PHCI) was constructed, which combined the variables of PHC coverage intensity (coverage of characterisation to the "Home Health" programme and health personnel ratio per population) using principal component analysis.
To compare the amount of social support received by near-centenarians and centenarians with younger individuals in prior studies, we combined the variables into a family, friends and total support sum score [ 29, 32].
Furthermore, a distributed leader follower consensus problem in multi-agent systems with unknown nonlinear dynamics is investigated by combining the variable structure approach and the adaptive method.
