SOLVE

This function computes the general inverse of X when it exists.
If X contains a degenerated dimension, return the original X.

An R package that implements the JICO algorithm [Wang, P., Wang, H., Li, Q., Shen, D., & Liu, Y. (2024). <Journal of Computational and Graphical Statistics, 33(3), 763-773>].
It aims at solving the multi-group regression problem. The algorithm decomposes the responses from multiple groups into shared and group-specific
components, which are driven by low-rank approximations of joint and individual structures from the covariates respectively.
