Sentence examples for quartile distance from inspiring English sources

†† Quartile distance = 0.75 * initial similarity.

Furthermore, we calculated the distance at which the initial similarity was 75% of its original value (the quartile distance).

Initial similarity reflects turn-over of species richness or composition at relatively small spatial distances, while the quartile distance describes turn-over at broad spatial distances [ 2].

The geographically and environmentally least complex Amazon subregion (Table 1) had the highest initial similarity and greatest quartile distance for species composition indicating a low beta diversity and a low species turnover even at large distances (Table 2).

The Amazon subregion also had the lowest initial similarity for species richness, but, in contrast, also the lowest quartile distance for this measure (Table 2), possibly reflecting greater regularity of the distance decay for similarity in species richness (Fig. 3 & 4).

The same was true at larger distances, as indicated by lower quartile distances, with the exception of the Amazon subregion (Table 2; see also Fig. 3 & 4).

All four C pools were estimated well using VNIR-DRS and PLSR (R2 > 0.77, residual prediction deviation > 2), ratio of performance to inter-quartile distance > 1.62.

Combining model outcomes derived from spectra using model averaging techniques improves or maintains the prediction status (as ratio of performance to inter-quartile distance) of vis-NIR and XRF models for a wide range of soil properties of agronomic importance.

Table 2 High, middle, and low range values for each parameter defined using quartiles   Distance to tectonic the plate boundary (km) PGA (g) Mean basin-wide slope Upper quartile LD > 1118.69 HP > 2.86 SS > 15.03 Interquartile range MD 94.34 1118.69 MP 0.68 2.86 MS 8.1 15.03 Lower quartile SD < 94.34 LP < 0.68 GS < 8.1.

The highly skewed distribution of the proportions of migrants, with an inter-quartile distance of about 10%, could have hampered detection of a potential association.

Data represent median (quartiles) distances in mm on the analog scales of Rating 3 assessed after sputum analysis, whereby 0 indicates a negative and 100 a positive (affirmative) answer.
