%description
The fusion learning method uses a model selection algorithm to learn from
multiple data sets across different experimental platforms through group
penalization. The responses of interest may include a mix of discrete and
continuous variables. The responses may share the same set of predictors,
however, the models and parameters differ across different platforms.
Integrating information from different data sets can enhance the power of
model selection. Package is based on Xin Gao, Raymond J. Carroll (2017)
<arXiv:1610.00667v1>.
