For example, if highly motivated and determined workers do persistently well in the labor market, conditioning on earlier labor market outcomes should help to remove selection bias that results from motivation or determination playing a role in receipt of VR.
First, a composite grayscale image was created by merging the two channels, to remove selection bias in thresholding.
However, including SES in the analysis will not remove selection bias that seems to be related to SES in some Interphone investigations (e.g., Hepworth et al. 2006).
Once the weights had been generated, we checked to see if the selection bias had been removed by performing bivariate tests against the treatment variable on all the variables used to remove selection.
These limitations, coupled with the wide confidence intervals we find in the empirical analyses, suggests that despite methodological improvements to remove selection biases from HIV prevalence estimates, it is critical to increase consent rates in HIV surveys.
In the second step, the counterselection was performed to remove selection marker using a reporter gene cassette without a cI- spc cassette to generate two transgenes, Tg-110 and Tg-220.
A random sampling method removes selection bias.
Alternatively we speculate and suggest that it may be possible to avert collapse by adopting a different strategy of removing selection pressures against shallow-water adapted AA and AB fish.
Thus, the action of natural selection, or more appropriately the effect of removing selection, is only revealed by differences in the local structure of the coexpression networks.
The setting of a universal, tax-funded health care and routine registration of the events of interest virtually removes selection bias.
