Sentence examples for event strata from inspiring English sources

Some Halimeda-rich horizons in the Western Mediterranean are not time-equivalent event strata as hypothesized by others.

Natural processes alone can move tephra around in profiles, and even create false secondary layers either above or below the actual air-fall event strata [31, 78, 161].

The Wei, Lin and Weissfeld method adapts the standard Cox model by creating a separate stratum for each event (first event, second event, third event, etc).. Within the 'second event' stratum, for example, the risk set at each event time includes all individuals still in follow-up, regardless of whether or not they have already experienced a first event.

For factors other than SES, we performed likelihood ratio tests for heterogeneity in the odds of an event, for strata in which there was at least one event.

Events like Strata are fascinating for the people who explore the new universe that data analytics unfolds.

Problems with convergence may emerge if there are too many event-order strata and/or a small number of episodes per stratum in both CFM [ 12] and CFPM.

In either case the over-dispersion ψ is best estimated from the Pearson chi-squared statistic, though neither this nor other estimates are consistent when data are sparse (few events per stratum) [ 13].

We assessed goodness-of-fit of the overfitting-corrected logistic models' by comparing the observed versus expected numbers of outcome events within risk strata, and by carrying out the Hosmer-Lemeshow test[ 18].

The necessary prespecification of stratum-specific type I error rates, when combined with (1) a stratum-specific event rate in the subgroup, (2) a stratum-specific primary endpoint, (3) a stratum-specific endpoint precision, and/or (4) a stratum-specific efficacy, satisfies the requirements for a subgroup stratum's "stand-alone" interpretation at the trial's conclusion.

on the seismic profile of the fourth acquisition data, seismic evens are relatively chaos, however, compared to the seismic profile of the third acquisition data, the continuity of seismic events of overlying strata gets improved, which indicates after coal mining, the strata tend to recover over time after compacting and depositing.

For the relative reductions in event rates, the stratum specific differences in means for the continuous outcome relative reduction (percentage change from baseline: (before−after)×100/before) were calculated and pooled across strata using a random effects meta-analysis.
