%description
The heterogeneous multi-task feature learning is a data integration method
to conduct joint feature selection across multiple related data sets with
different distributions. The algorithm can combine different types of
learning tasks, including linear regression, Huber regression, adaptive
Huber, and logistic regression. The modified version of Bayesian
Information Criterion (BIC) is produced to measure the model performance.
Package is based on Yuan Zhong, Wei Xu, and Xin Gao (2022)
