A Poisson mixed model with nonnormal random effect distribution
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper, we propose a random intercept Poisson model in which the random effect is assumed to follow a generalized log-gamma (GLG) distribution. This random effect accommodates (or captures) the overdispersion in the ...
Position-Restricted Substring Searching
(Springer Berlin / Heidelberg, 2006)
A full-text index is a data structure built over a text string
T[1, n]. The most basic functionality provided is (a) counting how many
times a pattern string P[1,m] appears in T and (b) locating all those
occ positions. ...
Nitrogen and Potassium Fertilization in a Guava Orchard Evaluated for Five Cycles: Soil Cationic Balance
(Soc Brasileira De Ciencia Do Solo, 2016-01-01)
Soil fertility evaluation through soil analysis traditionally does not consider interaction among elements. To include the interaction effect in interpretation of soil analyses, an experiment was conducted to evaluate the ...
Análisis de indicadores mediante modelos de regresión log-simétricos con componentes aditivos no paramétricos
(Bogotá - Ciencias - Maestría en Ciencias - EstadísticaDepartamento de EstadísticaUniversidad Nacional de Colombia - Sede Bogotá, 2020-07-15)
This work concerns with the statistical analysis of three financial indicators of a contact center. The available data of these financial indicators are strictly positive, asymmetric on the right and include extreme or ...
Exploring topsoil geochemistry from the CoDA (Compositional Data Analysis) perspective: The multi-element data archive of the Campania Region (Southern Italy)
(Elsevier, 2015)
Soil geochemistry is often investigated by considering a large number of variables, including major, minor and trace elements. Some of the variables are usually highly correlated due to coherent geochemical behaviour, but ...
