Following Bates (1996) and Craine, Lochester, and Syrtveit (1999), we present this process in continuous time by the following equations: dS S =(µ ... a marginal improvement relative to the linear benchmark. The paths of the linear and network out-of-sample errors appear in Figure 5.10. We see, not surprisingly, that both the lin...
