By explicitly including the sample as a dimension of the data matrix, we can scale from single-sample or pairwise comparisons to cohort-level analyses involving thousands of samples without having to open thousands of file connections and parsing as many files.
The power of the considered tests is influenced by a number of factors, including the sample size, the shift amplitude, the magnitude of the series and the location of the shift in the series.
The second study would have been strengthened by including the proportion of the sample represented by each individual COB.
However, by including the non-expert samples, it's possible to find low "consensus" values.
Accounting for the employment effects of skills in the wage equation either by including the non-employed in the sample and assigning them a very low wage or by estimating Heckman selection models yields returns to skills that are considerably larger than the baseline estimate (see Table 4 in Hanushek et al., 2015).
We also eliminated sampling bias by including the entire target population.
Measurements were collected over the period 1954 2000 by the Shanghai CDC and included the sampling date, factory name, and type of industry and job, all of which were abstracted from records maintained at municipal and district stations.
This research study was limited by several factors, including the convenience sample design and high socioeconomic status of participants.
To assess DIF when one-time and repeated testing are compared, we extended the sample of the N = 141 students by including parts of the sample of the N = 239 students whose data had been used in the stage of item selection in the test development process (see Fig. 1).
Moreover, by including normal samples in the analysis, we quantified the degree to which cell lines retain the Membranome up- and down- regulations observed in primary tumors with respect to their normal counterparts.
