1. Field parametric geostatistics - An alternative to tackle gold grade estimations
Abstract High anomalous grades are very common in gold deposits, whose presence requires careful treatment to prevent overestimation of metal content. Mineral resource analysts have worked on the estimation of several gold deposits, and none of the classical methods were able to avoid manual interventions, such as cutting high grades for local estimation or

2. Spatial prediction of soil penetration resistance using functional geostatistics
ABSTRACT Knowledge of agricultural soils is a relevant factor for the sustainable development of farming activities. Studies on agricultural soils usually begin with the analysis of data obtained from sampling a finite number of sites in a particular region of interest. The variables measured at each site can be scalar (chemical properties) or functional (in

3. Avaliação de técnicas geoestatísticas no inventário de povoamentos de Tectona grandis L.f. / Evaluation of geostatistics in inventory of Tectona grandis L.f. stands
The general objective of this work was to evaluate if estimates of wood volume obtained from geostatistics techniques are more accurate than those obtained from classical statistical techniques.The study was conducted in stands of Tectona grandis L.f. with the dendometric volume trait measured in 101 plots laid along a sampling spacing with UTM coordinates,

4. Análise do padrão espacial da mortalidade infantil utilizando geoestatística
O estudo da mortalidade infantil por meio da estatística espacial tem sua relevância ligada à identificação de regiões de risco com necessidade de intervenção dos órgãos de saúde. Dentre as técnicas de possível utilização encontra-se a geoestatística, que é empregada em trabalhos com dados continuamente distribuídos no espaço. O presente t

5. Estimação de contrastes de médias de tratamentos, de um experimento em blocos ao acaso, utilizando as análises clássica e espacial / Estimation of treatments means contrasts, in a random blocks model, using the classical and spatial analysis
Not controllable factors is common occur in experiments, they are responsible for the heterogeneity among parcels. Even executing the three experimentation basic principles in the design (repetition, randomization and local control), even so, may have correlation in errors and, therefore, spatial dependence in the area of study. If that autocorrelation struc
