The crime of intentional homicide in Brazil is worrying. In the northern region, this type of crime has been growing since 2020. In this sense, we decided to apply Kuldorff's prospective space-time scan statistics in order to identify emerging counties. We conclude that there are two emerging clusters of high relative risk (Amazonas and Pará) that...
The present work presented an alternative MCC to the Dunnett's test, called Ferbat's test. The test replaced the root of the mean square of the residue used within Dunnett's test with another non-biased $\sigma$ estimator. The distribution of the test statistics was determined by simulation using the Monte Carlo method. Comparing the performance ev...
The purpose of this paper was to develop two procedures of multiple comparisons based on methods of clustering means, that is, MGM and MGR tests. The first is based on the studentized midrange distribution, and the second based on the studentized range distribution. The tests showed performance equivalent to the performance of the compared tests. L...
TThe Multivariate Tests for the Vector of Means (TVMM) package has six functions: T2O function, which computes Hotelling original’s T² test; T2Boot function, which computes the parametric bootstrap version of the original T2 test; T2RobustBoot function, which computes the robust parametric bootstrapversion of the T2Boot test; LRTTrace function, whi...
Abstract The cold roller die process increases the tensile strength and decreases the ductility of steel wire. Annealing heat treatment is applied to restore mechanical properties, but this is a costly process. This research shows that it is possible to control the mechanical properties of ultra-low carbon steel wire inducing the Bauschinger effect...
A coleção Estudando o ambiente R é fruto de cursos ministrados sobre essa linguagem, bem como consultorias e estudos ao longo dos anos. Em 2005, quando ingressei na academia no curso de Engenharia Agronômica fiquei fascinado com a disciplina de Estatística no segundo semestre do ano corrente. Na sequência, acabo tendo o primeiro contato com o ambie...
The COVID-19 pandemic has spread rapidly around the world in a frightening way. In Brazil, the third country with the highest number of infected and deaths from the disease, it is important for government health authorities to identify the federation units that stand out in cases and deaths from this disease to target resources. The circular scan s...
Este artigo se propõe a construir um método para calcular probabilidades no futebol e comparar os resultados com o modelo do Departamento de Matemática da UFMG. Na metodologia apresentada, assumimos que os números de gols marcados pelos times em uma partida são independentes e seguem uma distribuição Poisson, em que a média reflete o fator ataque o...
Background
Brazil became the epicenter of the COVID-19 epidemic in a brief period of a few months after the first officially registered case. The knowledge of the epidemiological/clinical profile and the risk factors of Brazilian COVID-19 patients can assist in the decision making of physicians in the implementation of early and most appropriate me...
The COVID-19 pandemic spread quickly around the world in a frightening way. In Brazil, the third country in the world with the highest number of people infected and killed by the disease, it is important that the government health authorities identify the federation units that stand out in cases and deaths due to this disease for targeting resource...
In order to search for an ideal test for multiple comparison procedures, this study aimed to develop two tests, similar to the Tukey and SNK tests, based on the distribution of the externally studentized amplitude. The test names are Tukey Midrange (TM) and SNK Midrange (SNKM). The tests were evaluated based on the experimentwise error rate and pow...
A COVID-19 é uma infecção causada pelo coronavírus SARS-CoV-2, sendo que seus primeiros registros foram na cidade chinesa de Wuhan em dezembro de 2019, e foi considerada pela Organização Mundial da Saúde (OMS) uma pandemia mundial em março de 2020. No Brasil, a COVID-19 se espalhou atingindo as 27 unidades federativas (UFs). Com isso, as tomadas de...

We fitted the following seven distribution probabilities to the data of monthly average temperature in Mossoró, northeastern Brazil: Normal, Log-Normal, Beta, Gamma, Log-Pearson (Type III), Gumbel, and Weibull. To assess the goodness of fit the empirical distributions to the theoretical distribution, we applied the tests of Kolmogorov-Smirnov, Chi-...
The distribution of externally studentized midrange was created based on the original studentization procedures of Student and was inspired in the distribution of the externally studentized range. The large use of the externally studentized range in multiple comparisons was also a motivation for developing this new distribution. This work aimed to...
p>Objetivou-se elaborar uma tabela de probabilidades da ocorrência de valores mensais da pressão atmosférica em milibar, para Mossoró, RN, Brasil, a partir dos registros diários das pressões atmosféricas obtidas na Estação Meteorológica da Universidade Federal Rural do Semi-Árido em Mossoró, RN, referentes a uma série histórica de trinta e oito ano...
RESUMO: Analisou-se o ajuste das estimativas da evapotranspiração de referência (ETo) pelo método de Penman-Monteith-FAO à sete distribuições densidade de probabilidade (Normal, Log-Normal, Beta, Gama, Gumbel, Log-Pearson tipo ІІІ e Weibull) dos registros de dados meteorológicos da estação meteorológica Jerônimo Rosado da UFERSA (Universidade Feder...
