Mapping an uncertainty zone between interpolated types of a categorical variable
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Categorical data cannot be interpolated directly because they are outcomes of discrete random variables. Thus, types of categorical variables are transformed into indicator functions that can be handled by interpolation ...

Uma reflexão crítica sobre a teoria sociolinguística
(Pontifícia Universidade Católica de São Paulo (PUC-SP), 2010-01-01)
Um dos postulados da linguística do início do século XX é o de que o objeto da linguística deveria identificar-se com a parte homogênea dos fenômenos observáveis. Na segunda metade desse século, a sociolinguística representou ...

Simulação sequencial de atributos diagnósticos do solo
(Univ Federal Campina Grande, 2015-05-01)
The sequential simulation generates a set of equiprobable images with the same spatial variability of the experimental values. The aim of this study was to determine the spatial dependence of the diagnostic attributes of ...
Meta-analysis of the impact of plant invasions on soil microbial communities
(BMC, 2021)
Background One of the ecological impacts of exotic plant invasions may be alteration of the soil microbial community, which may cause changes to the diversity, richness and function of these communities. In order to explore ...
Age Categorization And Identification In A Community-dwelling Sample Of Brazilian Elderly

Non-parametric tests for small samples of categorized variables: A study
(2016-07-01)
This paper presents a study on non-parametric tests to verify the similarity between two small samples of variables classified into multiple categories. The study shows that the only tests available for this situation are ...
Using Bayesian networks with rule extraction to infer the risk of weed infestation in a corn-crop
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper describes the modeling of a weed infestation risk inference system that implements a collaborative inference scheme based on rules extracted from two Bayesian network classifiers. The first Bayesian classifier ...
