Correlação entre valores decendiais da evapotranspiração potencial calculados segundo métodos de Penman e de Thornthwaite e dados de evapotranspirômetros, na região de Ribeirão Preto

Correlação Probabilística de Bancos de Dados Governamentais

Statisticians and epidemiologists need to use data stored in databases from the National Unified Health System (SUS), “Bolsa Famı́lia”, and Cadastro Único to perform studies on the effects of social programmes held by the government in the incidence of some diseases in poor families. To support such studies, we designed a methodology and implemented a pipelining for data quality assessment, data...

Estudo Comparativo entre Proposicionalização e Mineração de Dados Multidimensional sobre um Banco de Dados Relacional

Propositionalization and multidimensional data mining are the two main approaches applied in a relational database during the pre-processing stage of a knowledge discovery project for relational classi cation. Much has been discussed whether there are di erences between them on the nal performance of the intelligent system, however, few studies have been performed with public data of real probl...

Uma Avaliação de Eficiência e Eficácia da Combinação de Técnicas para Deduplicação de Dados

Data Deduplication is the task of identifying and eliminating duplicate records in a single database. It is a complex process that involves several steps, including: defining blocking key, similarity function and indexing method. There are several approaches for each of these steps. In this context, the objective of this work is to find the best combination for such algorithms aiming to improve...

Medida de Correlação entre Padrões Pontuais de Origem-destino

When we use origin-destination survey data, we can be interested in verifying if the link between the two point patterns is or is not a result of randomness. In this paper we present a new measure of bivariate processes linking strength, find out its probability distribution and apply the method to data of car thefts location and its retrieving locations in Belo Horizonte. Resumo. Quando se uti...
