Comprehensive, developmental theories are sought that combine both between-person (BP) and within-person (WP) sources of information from results based on appropriate designs and tenable assumptions.
These assumptions are more tenable than alternative assumptions that would be required for crude analytic sample size calculations and that may yield underpowered and inefficient studies.
This manipulation made the proportional hazard assumption tenable and also made it unnecessary to include age as a covariate.
In complex sampling designs (incomplete block designs with several error strata, groups of possibly unbalanced experiments), one often performs mixed linear model analyses, when the normality assumption is tenable.
In principle, the assumption is tenable, based on the observation that the ACh volley output and the overall EPSC amplitude and properties remain reasonably constant over time.
If the missing completely at random assumption is tenable, then analyses making use of available data will generally produce valid inferences.
Because MTC typically assumes that statistical heterogeneity is constant between different pair-wise treatment comparisons, one could contrast these measures of heterogeneity across the relevant treatment comparisons to get a sense of whether or not this assumption is tenable.
While these assumptions are tenable in some settings, they are less appropriate for alcohol consumption.
In all these situations, provided the structuring assumptions are tenable, the analysis proceeds as in a density sampling case-control study wherein non-prevalent cases are proportional to respective person-time quantities and ultimately sustain an unbiased estimate of the IDR through the calculated cross-product ratio [ 30, 32].
Tenable as many of these assumptions may seem, a few of them such as assumption (5) is not really grounded because speed difference has something to do with safety.
For 50 years, the primary structures of lignins have been thought to be random, but for a number of reasons such an assumption is not tenable.
