Related to Square root of negative one: sigmaimaginary unit n. Symbol i The square root of -1, corresponding to the point (0,1) in the geometric representation of complex numbers as points in a plane. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © 201...
An H-nonnegative matrix B allows a decomposition in a negative definite, a nilpotent H-nonnegative, and a positive definite matrix, B=B鈯旴0鈯旴+. The interesting part is B0, as only Jordan blocks of size one and two occur. Determining a square root of B reduces to determining a ...
In affine term structure models the short rate is modelled as an affine transformation of a multi-dimensional square root process. Sufficient conditions to avoid negative volatility factors are the multivariate Feller conditions. We will prove their necessity for a 2-dimensional square root SDE with ...

Dislocations are linear defects in crystals and their motion controls crystals’ mechanical behavior. The dissipative nature of dislocation propagation is generally accepted although the specific mechanisms are still not fully understood. The inertia, which is undoubtedly the nature of motion for particles...
Examples include steepest gradient descent, which applies a simplified first-order Taylor, and conjugate gradient descent, which applies the Gram-Schmidt procedure to orthogonalize gradient vectors in each step of the descent. Another category of optimization method is based on the classical root find...
As a side note, I will be adding DFGLS unit root test in the next week or so and PP unit root test a few weeks later. I added the Leybourne-McCabe stationarity test a few months ago. Also added an ARFIMA sim with Lo’s modified R/S test for long memory to be added soon. https...
A positive correlation—one where the correlation coefficient is greater than 0—signifies that both variables tend to move in the same direction. When ρ is +1, it signifies that the two variables being compared have a perfect positive relationship; when one variable moves higher or lower...
