A simple diagnostic for time-series and panel-data regressions

Crump, Richard K.; Gospodinov, Nikolaj; Lopez Gaffney, … - 2024

We introduce a new regression diagnostic, tailored to time-series and panel-data regressions, which characterizes the sensitivity of the OLS estimate to distinct time-series variation at different frequencies. The diagnostic is built on the novel result that the eigenvectors of a random walk...

The fractional step method versus the radial basis functions for option pricing with correlated stochastic processes

Kagraoka, Yusho - In: International Journal of Financial Studies 8 (2020) 4, pp. 1-13

. This study applies the fractional step method and the radial basis functions to solve a PDE with a mixed derivative, and … step method calculates the option premium more accurately and much faster than the radial basis functions. Therefore, from … the numerical experiments, this study concludes that the fractional step method is more appropriate than the radial basis …
