If A is invertible then an inverse of A does not need to be unique.Square Matrix and Invertibility:There is a connection between the order of a matrix and its invertibility. Inverses are not defined for non-square matrices. However, this doesn't mean that all square ...
Another channel for this interaction could be the use of discretion on a selective basis to exercise the law where bribes are high. Crony capitalism could be of assistance in by-passing the law in queues which exist, ironically, because of the prevalence of a law. Given the relatively low ...
Explain a fastest way to do matrix multiplication? Multiply block matrices : \begin{bmatrix}1&-1\ 0& 2\ 2& 1\end{bmatrix} \cdot \begin{bmatrix}3&2\ 1& 0\end{bmatrix}. Why are projection matrices symmetric? Why can't a non-square matrix have an inverse? When is matrix multiplic...

By 'does not exist' we mean that the original matrix XTXXTX is not invertible, i.e. its inverse (XTX)−1(XTX)−1 does not exist. Usually this relates to the presence of eigenvalues with extremely small magnitude (or zero) in the matrix XTXXTX. This issue of non-invertabilty sug...
The reason for using at-the-money options to calculate implied volatility (IV) is based on theoretical foundations (e.g. Hull & White, 1987; Jorion, 1995). At-the-money options should produce the smallest bias in the case of non-constant volatility. They are also considered to be the ...
However, when looking at the inflation rate, there seems to exist evidence that when it changes, it has a higher impact on the interest rates of non-euro area countries than in euro area ones. Concerning the after-crisis period, the coefficients are negative, and higher for the countries ...
