For conversions associated with crossovers, the length was the average between the maximum tract length (the distance between the last heterozygous SNP before the conversion tract and the SNP that has the reciprocal LOH pattern indicative of the crossover) and the minimum length (the distance between the first and last homozygous SNPs of the tract).
The simulations we describe used the following parameters: effective population size, 2,000 (1,000 in each population); sample size, 200; genome length, 500,000; total generations, 25,000,000; mutation rate, 5 × 10−5 individual−1 generecombinationombination rate, variable; time between deletions, 50 generations; tract length, 500; distance factor, −20.
User input includes effective population size, sample (output) size, genome length, total number of generations, the number of generations between deletions of homogenous features, recombination rate, mutation rate, tract length, and the distance factor.
Second, simple GIS methods expressing physical separation between population and physicians were calculated per census tract, including distance to the nearest physician, and mean distance to the nearest three physicians.
For interstitial LOH events, the tract length was calculated as the average of the maximum tract length (the distance between the heterozygous SNPs flanking the LOH region) and the minimum tract length (the distance between the first and last homozygous SNP in the conversion tract).
The average distance between formants has become known as "formant dispersion" and has been used as an indirect proxy to body size or vocal tract length.
Census tracts whose distance to the nearest TRI facility was greater than 5 km but within 10 km were excluded from this analysis due to the small number of census tracts in this distance band.
The census tracts with distance to the nearest TRI facility in the third distance band (>0.5 km and <1 km) had the highest % non-white (54.8%) which was 8.7% higher than the statewide average Results indicate that on average, the highest proportion of non-white residents was in tracts that were between 0.5-1 km distance from a TRI facility.
Similarly, with a minimum length setting for fiber tracts short-distance connections cannot be discovered.
Then in each group of census tracts, the average distance between each tract and the closest TRI facility was calculated.
