A plethora of forest models were developed by transforming the dependent variable, which introduces bias if appropriate corrections are not applied when back-transformed. Many recognized still biased and original data sets no longer available, suggests ad hoc corrections. The present research presents a procedure for correction in absence needed information from summary statistics. Additionally, we realistic square root transformation based on truncated normal distribution. transformations...
In this paper we improve some existing results concerning the approximation of distribution extremes a 1-dependent and stationary sequence random variables. We enlarge range applicability error. An application to study scan statistics generated by Bernoulli trials is given.
Abstract Advancements in information technology led environmental scientists to the illusion that efforts should be mainly focused on developing models reduce uncertainty rather than adjusted existing uncertainty. As a result, relationships are represented by non‐parsimonious and suboptimal models, which many instances could even wrong. The objective of this research was provide modeling ecosystem processes with procedure supplies parsimonious correct results. transforms response variable...
The parameters of nonlinear forest models are commonly estimated with heuristic techniques, which can supply erroneous values. use algorithms is partially rooted in the avoidance transformation dependent variable, introduces bias when back-transformed to original units. Efforts were placed computing unbiased estimates for some power, trigonometric, and hyperbolic functions since only few transformations predicted variable have corrections estimated. approach that supplies results transformed...
The Tile Assembly Model, and its many variants, is one of the most fundamental algorithmic assembly formalism within DNA nanotechnology. Most research in this field focused on complexity assembling different shapes patterns. In cases, process intrinsically deterministic final product unique, while might evolve through several possible strategies. study we consider controlled dimensional tile structures according to predefined graphs. We provide approaches for developing such protocols, using...
Subterranean streams represent unique heterotrophic ecosystems, usually supported by organicmatter imported fromthe surface. Traditionally, the biological communities from subterranean were characterized as simple associations, with low diversity and species abundance, comprising mostly aquatic invertebrates connected few trophic links compared those of However, these features have not yet been described in wider context fluxes energy nutrients through food webs along a gradual switch...
Abstract To avoid the transformation of dependent variable, which introduces bias when back-transformed, complex nonlinear forest models have parameters estimated with heuristic techniques, can supply erroneous values. The solution for accurate provided by Strimbu et al. (Ecosphere 8:e01945, 2017) 11 functions (i.e., power, trigonometric, and hyperbolic) is not based on heuristics but could contain a Taylor series expansion. Therefore, objectives present study are to unbiased estimates...
Many experiments cannot feasibly be conducted as factorials. Simulations using synthetically generated data are viable alternatives to such factorial experiments. The main objective of the present research is develop a methodology and platform generate spatially explicit forest ecosystems represented by points with predefined spatial pattern. Using algorithms polynomial complexity parameters that control number clusters, degree clusterization, proportion nonrandom trees, we show can time...
