%description
Standard generalized additive models assume a response function, which
induces an assumption on the shape of the distribution of the response.
However, miss-specifying the response function results in biased
estimates. Therefore in Spiegel et al. (2017)
<doi:10.1007/s11222-017-9799-6> we propose to estimate the response
function jointly with the covariate effects. This package provides the
underlying functions to estimate these generalized additive models with
flexible response functions. The estimation is based on an iterative
algorithm. In the outer loop the response function is estimated, while in
the inner loop the covariate effects are determined. For the response
function a strictly monotone P-spline is used while the covariate effects
are estimated based on a modified Fisher-Scoring algorithm. Overall the
estimation relies on the 'mgcv'-package.
