Non- and Semiparametric Marginal Regression Models for Ordinal Response (1997)

Christian Gieger

this paper, we focus attention on cumulative regression models for ordinal responses (McCullagh, 1980) and multivariate extensions. Such models exploit, in a parsimonious way, the ordered scale of...

Additive, Dynamic and Multiplicative Regression (1995)

Fahrmeir, Ludwig, Gieger, Christian, Klinger, Artur

We survey and compare model-based approaches to regression for cross-sectional and longitudinal data which extend the classical parametric linear model for Gaussian responses in several aspects and...

Additive, Dynamic and Multiplicative Regression (1995)

Ludwig Fahrmeir, Christian Gieger, Artur Klinger

this paper we will focus on penalized least squares and likelihood methods as a unifying modelling and estimation approach. From this point of view, the smooth functions f j () are unknown, but...
