For this study multilevel regression analysis was applied.
A multilevel regression analysis was performed, and peak EMG data was compared.
Multilevel regression analysis of the responses showed that all groups made significant distinctions in patient priority depending on the severity of each characteristic in the vignettes.
An additional outcome of the multilevel regression analysis was information on the variance components of the between-schools and between-countries average school score in mathematics and in science (details presented in the Results section).
We did not use event-sampling procedure in its "pure" form, because event-sampling tends to produce varying time frames (e.g. >10 s), which leads to problems with the data synchronization for the multilevel regression analysis.
It should be pointed out that no error term was included in Equations 2a and 2b (below), an approach different from that used in a standard multilevel regression analysis.
Fidelity (doses received by parents, teachers and students, intervention relevance, management commitment, adherence and job satisfaction) was measured through the permanent products completed by the teams during the workshop period and related to the results through multilevel regression analysis.
Participants were stratified according to HIV-1 disease progression groups using a multilevel regression analysis model.
Based on evidence from this and other HIV cohorts [58], [59], we square root transformed CD4 counts in the multilevel regression analysis in order to attain normal distribution.
CD4 T-cell slopes in individual participants were estimated using a multilevel regression analysis model that predicted CD4 trends over time.
To account for the non-independance of observations within the same sibship, a multilevel regression analysis was applied with the MIXED procedure of SAS (version 9.2).
