Ajuste de modelos de fragilidade e riscos proporcionais aplicados a dados de retinopatia diabética

Abstract: Atualmente a análise de sobrevivência é uma das áreas que mais crescem no campo da análise estatística, com uma sólida teoria para ajustar modelos de regressão para estudar certos fenômenos, os quais têm, em sua estrutura, a característica de ter observações incompletas na amostra denominada censura. Embora esses modelos possam representar eficientemente o fenômeno em estudo em muitas situações, alguns deles não levam em consideração a existência de uma variável não observável presente na maioria dos estudos, … Show more

“…The values of AIC and BIC are similar, since both require the estimation of parameters, however, the second considers Bayesian and deviation information (Deviance Information Criterion -DIC) (Bolker et al, 2009). According to Brito et al (2020), the importance of using statistical models was verified, to identify those that most represent and help in the prediction of human diseases (Diabetic Retinopathy) and used parameters such as AIC and BIC to evaluate the most diverse distributions studied.…”
