Discovering patterns of time association among air pollution and meteorological variables
(Springer, 2021)
Lately, there is a concern about to air pollution, which leads to environmental
specialists discovering relevant causes of this phenomenon. Several
factors determine the level of pollution, but it is necessary to find ...
Variable parameter and double sampling (X)over-bar charts in the presence of correlation: The Markov chain approach
(Elsevier B.V., 2011-04-01)
The general assumption under which the (X) over bar chart is designed is that the process mean has a constant in-control value. However, there are situations in which the process mean wanders. When it wanders according to ...
On the use of correlated beta random variables with animal population modelling
(ELSEVIER SCIENCE BV, 2008)
We give reasons why demographic parameters such as survival and reproduction rates are often modelled well in stochastic population simulation using beta distributions. In practice, it is frequently expected that these ...
Poincaré plot indexes of heart rate variability: Relationships with other nonlinear variables
(2013-10-01)
The Poincaré plot for heart rate variability analysis is a technique considered geometrical and non-linear, that can be used to assess the dynamics of heart rate variability by a representation of the values of each pair ...

Multivariate association of wood basic density with site and plantation variables in Eucalyptus spp.
(2020-01-01)
Wood density, an important parameter for evaluating forest biomass productivity and wood product quality control, is influenced by a complex combination of variables of forest plantations, including environmental conditions ...
