MImat2mat

Computes the normalized mutual information (MI) between corresponding rows of two matrices
normalized by their individual information content, using the specified number of bins and spline order.

The biases introduced in association measures, particularly mutual information,
are influenced by factors such as tumor purity, mutation burden, and hypermethylation.
This package provides the estimation of conditional mutual information (CMI) and its
statistical significance with a focus on its application to multi-omics data. Utilizing
B-spline functions (inspired by Daub et al. (2004) <doi:10.1186/1471-2105-5-118>), the package offers tools to estimate the association between heterogeneous multi-
omics data, while removing the effects of confounding factors. This helps to unravel complex
biological interactions. In addition, it includes methods to evaluate the statistical significance
of these associations, providing a robust framework for multi-omics data integration and
analysis. This package is ideal for researchers in computational biology, bioinformatics,
and systems biology seeking a comprehensive tool for understanding interdependencies in
omics data.
