The key is, in the planning stage, we typically try to avoid any substantial imbalance.
We applied a balancing algorithm within the Random ForestsTM program (Salford Systems , Inc. to upweight small classes to equal the size of the largest target class and avoid any issues with imbalances between the number of presences and absences with the data parsed by province.
Ideally this colleague should be of equal status to avoid an imbalance of power.
During anaerobic fermentation, the respiratory chain is not functional and the NADH generated in connection with cell growth must be re-oxidized to NAD+ by formation of glycerol, in order to avoid an imbalance in the NAD+/NADH ratio (Nissen et al. [2000a]).
To avoid an imbalance between catalytic and noncatalytic residues, the model was trained on a dataset with a ratio of 11 between catalytic and noncatalytic residues.
This approach will be used to avoid an imbalance in drop-out rates between the two groups.
To avoid an imbalance between APC and standard care patients from each site, each participating site enrolled in blocks of three APC and six standard care patients.
This randomization technique was used to avoid an imbalance in the following variables: age, disease duration, and concomitant anti-rheumatic treatment [ 19].
In order to avoid an imbalance of chronic illness and general practice (care level) over the two groups, stratification for general practice and chronic illness (DM or COPD) was performed.
If an exposed patient could only be properly matched to one nonexposed patient, we accepted matching in a 1 1 ratio for the respective cohort in order to avoid an imbalance of characteristics and to retain the best possible matching.
