**The Discriminant of a Quadratic Equation Concept**

The discriminate of any equation in any degree plays an important role in determining the roots of that equation. In case of a quadratic equation with a positive discriminate, the roots are real while a 0 discriminate indicates a single real root....

In the case of discriminant validity, you could show that there is no correlation at all. Correlation is measured by a correlation coefficient , r, on a scale of -1 to 1, where r=-1 is perfect negative correlation, r=1 is perfect positive correlation, and r=0 is no correlation at all....

- The discriminant of a polynomial is the resultant of the polynomial with its derivative. Its purpose is to detect whether the polynomial has any multiple roots. (If a root has mulitiplicity > 1, then it will also be a root of the derivative).
- In algebra, the discriminant of a polynomial is a polynomial function of its coefficients, which allows deducing some properties of the roots without computing them. […] for a polynomial of an arbitrary degree, the discriminant is zero if and only if it has a multiple root, and, in the case of real coefficients, it is positive if and only if the number of non-real roots is a multiple of 4.
- "Fisher's Discriminant Analysis" is simply LDA in a situation of 2 classes. When there is only 2 classes computations by hand are feasible and the analysis is directly related to Multiple Regression. LDA is the direct extension of Fisher's idea on situation of any number of classes and uses matrix algebra devices (such as eigendecomposition) to compute it. So, the term "Fisher's Discriminant
