In the PP method, simple regression relationships were developed from individual plot data where an assumed diameter distribution had been fitted to the observed plot distribution. The data were combined over many plots with a range of stand conditions to form a representative data set, and ...
only 214 trees existed in undisturbed plot, in which basal area was 3.385 m2/ha.Pinus koraiensis(Pk) had the largest DBH in both disturbed and undisturbed plots, which was 56.2 cm and 55.5 cm, respectively.Populus davidiana(Pd) andBetula costata(Bc) only existed in the disturbed plot, and...
The goal of rjqpd is to implement the Johnson Quantile-Parameterised distribution system in R. It provides the density function, cumulative distribution function, quantile function and random sampling function in their usual form:djqpd - calculates the density function (PDF) pjqpd - calculates the...
(d) \(\mathcal{E}\in \left[-\mathrm{4,4}\right]\) The scatter plot in Fig. 3 illustrates the sample distribution, and the classification results. Figure 3 Scatter plots of source samples (upper plot) and target samples (lower plot). We visualize the first and second dimension. Two...

r plot of the size distribution generally occurred between 30 and 40 μm radius. The slope B ( dN dlogr = Ar −B) in the 5–25 μm radius range averaged 2.3 while in the 40 to 100 μm radius range B averaged 6.7. A complete atmospheric aerosol size distribution for the 0.01–...
