The challenge is to balance statistical efficiency and respondent burden to minimize the overall error in the survey responses.
ECMLM effectively increases the potential to balance statistical power and computing speed.
DO and CC mice are more expensive than other laboratory mice, Chiu notes, and costs must be balanced with statistical power requirements, echoing the study design issues raised by DeVito.
Table 4 shows that the 4 groups were balanced (no statistical difference) for all of the predictors of participation, namely, gender, occupational classification of father, occupational classification of mother, family composition, parental monitoring, spending money, early school leavers and frequency of drunkenness.
The adaptive ensemble methods balances statistical precision with computational efficiency; we conservatively use 1,000 as a minimum final ensemble size such that a p-value as low as 0.001 can be assigned.
This software produces a manageable number of combinations of attributes and their respective levels (or scenarios) to develop a survey questionnaire, balancing the statistical requirements with the need to avoid overburdening the respondent with work.
Since Monte Carlo histories are never infinitely long, the sum in Eq. (19) has to be truncated at some window W. For its choice, one has to balance the statistical error, which increases with larger windows, with the systematic error from neglecting the contributions beyond W.
The results of comparative observational trials of liver resections can be problematic because of the large number of covariates that need to be balanced by complex statistical methods.
For single-regressions, the increase in noise (i.e. decrease in raw SNR per single image) at low-TR is nearly balanced by the statistical advantage of the increased number of samples (timepoints), resulting in peak Z-stats being similar across TRs.
