The Zero, One and Zero-and-one-inflated New unit-Lindley Distributions
Conteúdo do artigo principal
Resumo
Neste artigo propomos as distribuições New unit-Lindley inflacionada em zero, em um e em zero e um como extensões naturais da distribuição New unit-Lindley
para modelar respostas contínuas medidas nos intervalos $[0,1)$, $(0,1]$ e $[0,1]$. Estas distribuições foram construídas a partir de combinações convexas entre a distribuição New unit-Lindley e as distribuições degenerada em zero, em um e Bernoulli. Elas também contam com uma série de propriedades interessantes tais como serem membros da família exponencial além de contar com formas as funções de distribuição acumulada, quantil e para os momentos. Aspectos inferenciais e estruturas de regressão são discutidas neste trabalho bem como um estudo de simulação Monte Carlo para avaliar a performance dos coeficientes regressores. Por fim, trazemos uma aplicação a dados reais sobre a taxa de suicídio no ano de 2016.
