Research in neuroscience has seen a recent trend toward the extension of receptive field (RF) estimation techniques and theoretical principles from linear to non-linear models. This development has ...

We consider a quadratic regression model and derive D-optimal exact designs for estimating any given subset of the model parameters. Our results complete recent findings of Krafft and Schaefer (1995) ...

This article describes three approximation methods I used to solve the growth model (Model 1) studied by the National Bureau of Economic Research's nonlinear rational-expectations-modeling group ...

Fitting SPX and Vix smiles simultaneously is one of the most challenging problems in volatility modelling. A long-standing conjecture is that it may not be possible to jointly calibrate these two ...

Indian users searching on Google on Wednesday (Nov 12) were greeted by an animated mathematical doodle featuring the quadratic equation: ax2+bx+c=0. This widely used formula, which has applications ...
