Investigating the impact of GDP and distance variables in the gravity model using sign and rank tests [PDF]
Eastern Journal of European Studies, 2021 The gravity model of trade has been a workhorse of international economics over the last fifty years. The main variables incorporated in the standard gravity model of trade are gross domestic product of trading countries and distance between them.

A novel modification to backpropagation sample selection strategy [PDF]
, 1997 Random sample selection method in backpropagation results in convergence on the error (root of mean squared error, RMSE) surface. These problems, which are caused by the extreme (worst-case) errors, can be solved by a different sample selection strategy.

STANDARD MBTHOD OF RMSE CALCULATION FROM POLYNOMIAL RECTIFICATION
Journal of Engineering, 2002 Image quality and geometric accuracy of SPOT data are essential elements in cartographi: applications. The evaluation of geometric accuracy of SPOT data is carried out by analysis and quantification of the errors in geometric correction. For this purpose, many programs are designed to correct the image geometrically (polynomial transformation) and to ...

Randomizing the trapezoidal rule gives the optimal RMSE rate in Gaussian Sobolev spaces
Mathematics of Computation, 2023 Randomized quadratures for integrating functions in Sobolev spaces of order α ≥ 1 \alpha \ge 1 , where the integrability condition is with respect to the Gaussian measure, are considered. In this function space, the optimal rate for the worst-case root-mean-squared error (RMSE) is established.
