In addition, to be certain that the activated sample windows are of a signal of considerable energy, the ACTIVE sub-state should be triggered with a t vad such that (t_{text {vad}} gtrsim t_{text {change}}).
The idea is that in certain contexts, the sample in the American Community Survey is too small to say something significant.
Strictly, these structures should be reweighted, as it is not certain that the phase space sampled by the low-level methods is the same as with the higher-level methods [19].
In certain cases, we observed that the sample weight initially increased, leading to a weight retention ratio y t higher than 1, and then it gradually decreased.
We cannot, therefore, be certain that our sample is representative of the population of Canadian family physicians (despite a concerted effort to maximise representativeness by seeking participants of various age groups, practice settings, geographic locations, etc).
This study has certain limitations, including the fact that the sample is not necessarily representative of the population of Brazilian psychiatrists.
Namely, for a particular initial condition characterized by molecular concentrations and particle locations, one can record the time at which the next molecule performs the event in question, be it translocation or molecular collision, from which a certain CDF can be derived given that the sample of experiments is large enough.
While the overall sample size of the study allowed sufficient power to reduce the probability for a Type II error in the primary analysis, it is possible that the sample sizes for certain predictor variables (i.e. Aboriginal status) were not sufficiently large to establish a statistically significant.
Because we suspected that the sample size of certain racial/ethnic subgroups may have been too small to allow detection of SNP*race/ethnicity interactions, and because the allele frequencies for 13 of the 25 SNPs differed by more than 0.20 between the ethnic groups, we repeated all of our analyses in the subsample of white participants, the largest racial/ethnic subgroup.
It was anticipated that it might be difficult to recruit individuals that fulfil certain categories of the sampling frame and efforts were made to ensure that participants were as representative of South African migrant health workers as possible.
