The U.S. central banking system—the Federal Reserve, or the Fed—is the most powerful economic institution in the United States, and perhaps the world. Its core responsibilities include setting ...

The simplest form of regression in Python is, well, simple linear regression. With simple linear regression, you're trying to ...

Specifically, the method relies on a simulated nonlinear least squares objective function appropriately adjusted so as to obtain consistent estimates of the parameters of interest. We illustrate the ...

The demand curve is a graphical representation of the relationship between the price of a good and the quantity demanded.

The Centre for Multilevel Modelling (CMM) is a research centre based at the University of Bristol. Our researchers are drawn from the School of Education. We collaborate with a range of researchers in ...

The nonlinear distortion from directly modulated lasers (DMLs) is a major challenge to meet the explosive data traffic for improving optical communication systems performance. To practically and ...

We investigated the performance of a CVRC-based nonlinear equalizer designed to compensate for fiber-optic nonlinearity when varying the activation function. The performance tended to deteriorate ...
