WebJun 26, 2024 · 1 Answer. Yes, because if the determinant is zero, then the system is either inconsistent (no solutions), or it has infinitely many solutions. Assuming the determinant is defined (which means that you must have a square matrix), you can just take the inverse of the matrix. If the inverse exists, this will give you exactly one, unique solution. WebOct 31, 2015 · In a linear relationship, the variables move in the same direction at a constant rate. This means if we have non-monotone related variables we can observe a zero correlation even though they are not independent. To illustrate this say for example we have a f ( x) = x 2, using python to evaluate the function.
