### ENAR 2017 SPRING MEETING SHORT COURSES

Description: All standard regression models have assumptions that must be verified for the model to have power to test hypotheses and for it to be able to predict accurately. Of the principal assumptions (linearity, additivity, distributional), this course will emphasize methods for assessing and satisfying the first two.

### Contrast trees and distribution boosting

quantile regression jconditional distribution estimation I n statistical (machine) learning one has a system under study with associated attributes or variables. The goal is to estimate the unknown value of one of the variables y, given the known joint values of other (predictor) variables x= (x 1, x p) associ-ated with the system.

scedastic ordered logistic regression (HOLR) and heteroscedastic censored logistic regression (HCLR) (Messner et al. 2014b). It is useful to note that HCLR ﬁts the same model as HELR, with the only difference being that the HCLR parameters optimize the con-tinuous predictive pdf, as opposed to the quantile thresholds (Messner et al. 2014b).

Concerning the problem of FDC prediction in ungauged basins, regional models proposed in the literature follow a variety of dif- ferent approaches and conceptualizations, which are covered e.g. by Castellarin et al.

They also proposed two additional logistic regression-based approaches for postprocessing precipitation: heteroscedastic ordered logistic regression (HOLR) and heteroscedastic censored logistic regression (HCLR) (Messner et al. 2014b).

estimation via CSH regression models as this approach allows the estimation of both CSHs (rate) and cause-specific cumulative probabilities (risk). CSH regression models are quite useful because they are easy to fit (since we only need to censor for the competing event),4 and unlike models on subdistribution hazard, they give a simple
