Abstract in Portuguese
Neste trabalho consideramos a análise do modelo de calibração comparativa estrutural quando a característica a ser medida formam grupos de diferentes médias e variâncias. Estimativas de momentos e de máxima verossimilhança dos parâmetros envolvidos no modelo e as suas variâncias assintóticas são obtidas. Apresentamos um estudo do modelo de calibração comparativa com ponto de mudança, obtendo-se estimadores dos parâmetros do modelo quando existe a presença do ponto de mudança. Finalmente apresentamos um modelo de calibração comparativa estrutural que considera um efeito aleatório atribuído aos manipuladores dos instrumentos usados para medir uma característica num conjunto de indivíduos, a análise deste modelo está baseado no modelo misto linear geral

Abstract in English
In this thesis, we consider the structural comparative calibration model in situations where the data can be splited into subgroups where the distribution of the quantity being measured presents different means and variances. Moment and maximum likelihood estimators are considered and their asymtotic behavior studied. An study of the comparative calibration model with change-point is considered, and parameter estimates when there is a change-point are presented. Finally, we present a comparative calibration model with random effects due to the present of multiple operators, which are measuring the same unknown caracteristic. Inference procedures for such model is based on the general linear mixed model
