Influence diagnostics on the coefficient of variation of elliptically contoured distributions
Riquelme-Álamos, Marco; Leiva, Víctor; Galea, Manuel; Sanhueza, Antonio (2011)In this article, we study the behavior of the coefficient of variation (CV) of a random variable that follows a symmetric distribution in the real line. Specifically, we estimate this coefficient using the maximumlikelihood ...

On a logistic regression model with random intercept: diagnostic analytics, simulation and biological application
Tapia, Alejandra; Leiva, Víctor; Galea, Manuel; Werneck, Rachel (2020)This article proposes a methodology for diagnostics in a logistic regression with random intercept motivated by a biological study. The methodology includes local and global influence techniques allowing us to contrast the ...

Robust linear functional mixed models
Riquelme-Álamos, Marco; Bolfarine, Heleno; Galea, Manuel (2015)In this paper we propose a linear functional model with normal random effects and elliptical errors, thus extending the standard normal models considered previously. The corrected score approach (Nakamura, 1990) is used ...
