Maximum Agreement Linear Predictors
Taeho Kim, Pierre Chausse, Matteo Bottai +4
This paper studies predictor functions motivated by maximizing a measure of agreement with the predictand. Specifically, it examines distributional properties and predictive perfor…
Modeling sign concordance of quantile regression residuals with multiple outcomes
Silvia Columbu, Paolo Frumento, Matteo Bottai
Quantile regression permits describing how quantiles of a scalar response variable depend on a set of predictors. Because a unique definition of multivariate quantiles is lacking,…
Parametric Modeling of Quantile Regression Coefficient Functions with Longitudinal Data
Paolo Frumento, Matteo Bottai, Iván Fernández-Val
In ordinary quantile regression, quantiles of different order are estimated one at a time. An alternative approach, which is referred to as quantile regression coefficients modelin…
Mean survival by ordered fractions of population with censored data
Celia García-Pareja, Matteo Bottai
We propose a novel approach for estimating mean survival time in the presence of censored data, in which we divide the population under study into survival-ordered fractions define…
