Deciles

Here we cannot assume that a single value of standard deviation is applicable. Insert control materials in total numbers approximately as recommended above. However, there should be at least two levels of analyte represented, one close to the median level of typical test materials, and the other approximately at the upper or lower decile as appropriate. Enter values for the two control materials on separate control charts. Duplicate a minimum of five test materials, and insert one procedural blank per ten test materials. 

It will be well to clarify and amplify the meaning of metabolic peculiarities since these play a highly important role in our discussion. Briefly, every individual gives evidence of metabolic peculiarities if he has, for example, in his blood, urine, saliva, or tissues, some constituent at a level substantially different from the average, for example, in the 1st or 10th decile of a representative human population. If the level is far removed from the average, the peculiarity is...

Mean serum levels in a survey in Finland were found to be around 60ng/ml. Lower levels of blood Se were found in subjects with cancer (82-84) than in matched control, particularly in those cases on the lowest quintiles or deciles. In Northwest Washington State (85) and in men of Japanese ancestry in Hawaii (86) no relationship was found with cancer and probably to be significant other concomitant factors have to be present. 

The only other quantile systems that are used with any regularity are quintiles, deciles and centiles. There are four quintiles, which divide data into five ranges, nine deciles for 10 ranges and 99 centiles that produce 100 ranges. The ninth decile is thus equivalent to the ninetieth centile and both indicate a point that ranks 10 per cent from the top of a set of values. 

In 1998, the ECST (European Carotid Surgery TriaUsts Collaborative Group 1998) showed that there was no benefit from surgery in patients with 30-49% stenosis or 50-69% stenosis (defined by their method), but that there was major benefit in patients with 70-99% stenosis. When the results of the ECST were stratified by decile of stenosis, endarterectomy was only beneficial in patients with 80-99% stenosis. The 11.6% absolute reduction in risk of...

This experiment serves several purposes. It was undertaken mainly to familiarize Starks C. P. with the model. Also, it shows how unselected compounds rank against the NCI file. If one uses the scale of the training set, then 23-30 of the 1000 fall in the highest decile and 350-500 in the lowest decile, depending on the version of the model. 

Another purpose of the test of 1000 is to compare the relative performance of an experienced chemist with the performance of the model, not to see which is better (undoubtedly the chemist) but to see if there are some things the model will catch which are not obvious to the chemist. In fact, review by the chemist of the 30 compounds which scored in the top decile, led him to revise his opinion of activity from originally 15 to almost all, i. e., 28 as possibly active. A second chemist, Frank Williams, performed the review.

Piperonvl bu to side (PBO) science is half a century old, With five deciles of use. it must do somethin important and do it well. As the first major insecticide synergist, PBO established the principle and practice of making the best use of valuable pest control agents. The term insecticide synergist is synonymous with PBO. It always dominated the field and still leads the way. 

Note This data is derived from over 31,000 compounds. Each sub-family is represented by between 3 and 29 targets, kcal/mol/non-hydrogen atom. Mean of upper decile of compounds ranked by potency. ... 

Finally, Table 8.28 lists base salaries, bonuses, consulting fees, and commissions by salary quartiles and deciles. There is a wide spread in base salaries, from 48,000 to 105,000, depending on a variety of factors including job function, company, location, and employee perfonnance. 

Calculated from USA tolerance and 9th decile consumption figures minimum figures since small consumption commodities are excluded. USA tolerances used for calculations were those in effect during 1964-1970. Tolerances for DDT and dieldrin on certain commodities were reduced during 1968-69 however, the higher tolerances were used in the calculations.
