This suggests that the data on the fraction of college graduates should be treated as censored data.
We obtain similar results if limiting the sample to students who enroll in colleges with non-missing data on the fraction of applicants admitted.
This type of simulations should be done on case by case bases using field data on the fraction of dissolved and oil droplets, oil droplet size distribution, and initial oil degrading microbial concentrations.
In attempt to improve the latter, experiments were conducted in a 101.6 mm gas liquid flow loop at Cranfield University's Oil and Gas Engineering Laboratory and data on the fraction of droplets were collected in the annular flow regime by measuring the film velocity, from which the droplet fraction was calculated.
Similarly, prior to 1982 no data on the fraction of winter barley and spring barley were available.
No data on the fraction of winter and spring cereals, respectively, were available for 1955 61, and these data points were omitted in the analyses.
With respect to some of the complications, there are many causal factors and no reliable data on the fraction attributable to diabetes.
The analyses use data on the fraction of the UK population at different levels of exposure, and estimates of the risk associated with each, relative to the optimum exposure.
Crop residue flows and the fractions used as feed were derived from the databases for 2000 using data on harvest indices (the ratio of grain to total plant biomass) and the usage of harvest residues as well as data on the fraction of available crop residues used for feed [38,49,56].
Finally, no data on the fraction of winter and spring rye are available from 1955 61 and 1979 98, but in Denmark spring rye is generally sown on very few hectares only [ 42], and we regarded rye as winter rye unless otherwise specified [see also [ 32]].
