Modeling air pollution using partially varying coefficient models with heavy tails
Jeldes, Nicole; Ibacache-Pulgar, Germán; Marchant, Carolina; López-Gonzales, Javier Linkolk (2022)The increase in air pollution levels in recent decades around the world has caused a negative impact on human health. A recent investigation by the World Health Organization indicates that nine out of ten people on the ...

Modeling environmental pollution using varying-coefficients quantile regression models under log-symmetric distributions
Sánchez, Luis; Ibacache-Pulgar, Germán; Marchant, Carolina; Riquelme, Marco (2023)Many phenomena can be described by random variables that follow asymmetrical distributions. In the context of regression, when the response variable Y follows such a distribution, it is preferable to estimate the response ...

Semiparametric additive beta regression models: Inference and local influence diagnostics
Ibacache-Pulgar, Germán; Figueroa-Zúñiga, Jorge I.; Marchant-Fuentes, Carolina (2021)In this paper, we study a semiparametric additive beta regression model using a parameterization based on the mean and a dispersion parameter. This model is useful for situations where the response variable is continuous ...
