%description
The goal of this package is to cover the most common steps in Loss Given
Default (LGD) rating model development. The main procedures available are
those that refer to bivariate and multivariate analysis. In particular two
statistical methods for multivariate analysis are currently implemented –
OLS regression and fractional logistic regression. Both methods are also
available within different blockwise model designs and both have
customized stepwise algorithms. Descriptions of these customized designs
are available in Siddiqi (2016) <doi:10.1002/9781119282396.ch10> and
Anderson, R.A. (2021) <doi:10.1093/oso/9780192844194.001.0001>. Although
they are explained for PD model, the same designs are applicable for LGD
model with different underlying regression methods (OLS and fractional
logistic regression). To cover other important steps for LGD model
development, it is recommended to use 'LGDtoolkit' package along with
'PDtoolkit', and 'monobin' (or 'monobinShiny') packages. Additionally,
'LGDtoolkit' provides set of procedures handy for initial and periodical
model validation.
