This is the reason for which we came out with our own skim procedure rather than relying on heuristic approaches, which usually have more stringent assumptions with regard to the number of inliers within the correspondence set.
Moreover, the overwhelming majority of published reports use either completers only or LOCF techniques that have more stringent assumptions (i.e., completers only) or no theoretical foundation (i.e., LOCF) and are known to produce biased estimates in many circumstances.
We will conduct sensitivity analyses, making progressively more stringent assumptions regarding the outcomes of participants with missing data.
27 For assessing the impact of loss to follow-up across studies, we will conduct sensitivity analyses making progressively more stringent assumptions regarding loss to follow-up in intervention and control groups.
For variables with more than two categories, multinomial logit regression models will be used to analyze neighborhood variation in these measures of physical activity as preliminary analyses showed that the more stringent assumptions associated with an ordered cumulative logit model were not met.
Proof of Theorems 2 and 8 Fix 0 < p < 1 < c < 2, and an auxiliary constant c 1 with c < c 1 < 2. For the proof of Theorem 8, we make the more stringent assumption that c < c 1 < 3. We will show that as long as N is sufficiently large, there exists a p-c-chaotic and p-unstable N-dimensional bi-quadratic cooperative Boolean network.
However, DP requires more stringent system modeling assumptions, i.e., requiring the prior knowledge of the probabilistic characteristics of the EH process, data arrivals, and channel states.
We thus conclude that both methods, being upwind schemes designed for the ACM, have the same performances in terms of accuracy and convergence speed, even though the revised method is more complex with less stringent assumptions made, while the original CB method is simpler due to the use of extra simplifying assumptions.
If Z i is not measured with error (eg, date of birth), if Z i is noncontinuous (eg, ordinal), or if there is a phase-in region around the cutoff, then regression discontinuity designs can be implemented under a more stringent but often plausible assumption that there are no other reasons for a discontinuity in potential outcomes at the threshold other than treatment assignment.
There were several statistically significant violations of the more stringent double monotone homogeneity (non-intersection) assumptions, but strong evidence of violation was only seen for a minority of symptoms in certain sites.
Our empirical investigation is aimed at testing the assumption that firms that face more stringent employment legislation tend to adjust the structure of their employment in ways that differ from firms that face more flexible legislations.
