%description
Fits linear regression, logistic and multinomial regression models,
Poisson regression, Cox model via Global Adaptive Generative Adjustment
Algorithm. For more detailed information, see Bin Wang, Xiaofei Wang and
Jianhua Guo (2022) <arXiv:1911.00658>. This paper provides the theoretical
properties of Gaga linear model when the load matrix is orthogonal.
Further study is going on for the nonorthogonal cases and generalized
linear models. These works are in part supported by the National Natural
Foundation of China (No.12171076).
