gamboostLSS
implements boosting algorithms for fitting
generalized linear, additive and interaction models for to potentially
high-dimensional data. Instead of modeling only the mean,
gamboostLSS
enables the user to model various distribution
parameters such as location, scale and shape at the same time (hence the
name GAMLSS, generalized additive models for location, scale and
shape).
For installation instructions see below.
Instructions on how to use gamboostLSS
can be found
in the gamboostLSS
tutorial.
Details on the noncyclical fitting method can be found in
