To take into account the repeated-measures design of the study, any missing follow-up occasion, variation in duration of follow-up, and bilaterality, and also to allow for confounder correction (Pijls et al. 2011), a generalized linear mixed model (GLMM) was used (R software version 2.12.0), which is considered to be the primary analysis method for this type of clinical study (DeSouza et al. 2009).
On occasion, variations in reagent concentrations or protocol were advantageous.
Anyway, you have to admit that directors here come up with some surprising and, on occasion, illuminating variations on what to do with comestibles.
Under controlled growth conditions on two distinct occasions, more variation was observed in transcript profile between homozygous wild type controls than was observed between two sib E3 plants grown on single occasions.
The more complex the tasks (e.g. complex arithmetic tasks or reading words from very specific word classes), the more adequate is the parametric modelling of stimulus features, since in many occasions authentic variation in stimulus properties cannot be matched exactly between different conditions, but only on average.
Second, because in weeks 4 and 8 each subject was reminded of and anchored on her responses on the previous measurement occasion, the interassay variation was low in the survey instruments.
Repeatability on different occasions was calculated by using data from patients who were measured on at least two different occasions and by determining the between-occasion coefficient of variation.
The mean between-occasion coefficient of variation was calculated by using the data of patients measured on at least two occasions and was 9.7% (Table 3).
And breadth and diversity of opinion may require not just a political and cultural range, but, on occasion, reflect the variations between urban and rural, older and younger, poorer and wealthier, the innovative and the status quo".
Among the operating variables studied, reaction extent had the most significant influence on phase equilibrium possibly due to changes in the hydrophilicity of the reaction medium occasioned by compositional variation in the course of the reaction.
The between-occasion coefficient of variation of TwPdi was 9.7%, comparable with data from healthy volunteers.
