Finding Redundant Variables in the Data

The repository has the codes to identify co-linear (linearly dependent columns in a data) using linear algebra techniques.

Here three methods are implemented:

• Symbolic Method using Sympy.
• Numerical method using SVD method.
• Implementation of MATLAB null(x, 'r').

For numerical technique tol can be adjusted to set threshold below which variables can be removed. To be strict choose higher value of tol.
