Log‐symmetric quantile regression models

Abstract: Regression models based on the log-symmetric family of distributions are particularly useful when the response variable is continuous, positive, and asymmetrically distributed. In this article, we propose and derive a class of models based on a new approach to quantile regression using log-symmetric distributions parameterized by means of their quantiles. Two Monte Carlo simulation studies are conducted utilizing the R software.The first one analyzes the performance of the maximum likelihood estimators, the Ak… Show more

“…An issue to be further studied is the efficiency of the variables in the securities markets [51,52]. Moreover, generalizations to multivariate models [53], incorporation of temporal [54], spatial [55] and quantile [55,56] regression structures in the modeling, as well as errors in variables [57] and PLS regression [37], should also be considered using the variables: GHSI, country risk, and OECD membership as relevant in relation to countries' economies.…”

“…A multivariate version of the RBSARMAX model might also be of interest [ 12 , 50 ], and local influence diagnostics could be derived, allowing the detection of potentially influential cases [ 16 ]. Other aspects for future study using this new model are associated with quantile, spatial, partial least squares, principal components, and sampling structures [ 51 , 52 , 53 , 54 , 55 , 56 ].…”

“…Local influence techniques have been developed for different non-Gaussian and asymmetrical models; see, for example, refs. [16,17,[23][24][25]. As a motivation to develop our work, next, we show the inadequacy of the usual mean regression when analyzing real-world data with an asymmetrical distribution.…”

“…94-125). Based on these two previous considerations, a similar approach to generalized linear models (GLM) can be used for quantile regression; see [15][16][17]. In GLM, the mean is modeled, which is besides one of the parameters of the assumed distribution.…”
