2. Distribuições em série de potências modificadas inflacionadas e distribuição Weibull binominal negativa / Inflated modified power serie distribution and Weibull negative binomial
In this paper, some result such as moments generating function, recurrence relations for moments and some theorems of the class of modified power series distributions (MPSD) proposed by Gupta (1974) and of the class of inflated modified power series distributions (IMPSD) both at a different point of zero as the zero point are presented. The standard Poisson

4. Classe de distribuições série de potências inflacionadas com aplicações
Este trabalho tem como tema central a classe de distribuições série de potências inflacionadas, em que o intuito é estudar suas principais propriedades e a aplicabilidade no contexto bayesiano. Esta classe de modelos engloba as distribuições de Poisson, binomial e binomial negativa simples e as generalizadas e, por isso é muito aplicada na modelagem

5. A STOCHASTIC MODEL FOR THE NUMBER OF TRANSACTIONS IN THE BRAZILIAN CAPITAL MARKET: WITH APPLICATION IN SIMULATING DAILY RETURNS OF STOCK IN THE FRAMEWORK OF A TIME DEFORMATION MODEL / UM MODELO ESTOCÁSTICO PARA O NÚMERO DE NEGÓCIOS COM AÇÕES DO MERCADO DE CAPITAIS BRASILEIRO: COM APLICAÇÃO EM SIMULAÇÃO DE RETORNOS DIÁRIOS ATRAVÉS DE DEFORMAÇÃO TEMPORAL
This thesis proposes a new stochastic model for the daily number of transactions with stocks in the Brazilian capital market. The model, which we call ZINB-HF (Zero ¿ Inflated Negative Binomial Harvey- Fernandes), is an extension of a local scale model for count data. In it, the daily number of transactions follows a serially correlated negative binomial di
