## Ill-Conditioned

Statistics Definitions > A mathematical problem or series of equations is ill-conditioned if a small change in the independent variable (input) leads to a large change in the dependent variable (output). This can lead to computational problems. For example, if a system of equations is ill-conditioned, the solution exists, but it if very difficult to find. Well-conditioning is one of the requirements for well-posed problems. Therefore,...
