The EWQR cost function can be used as the basis for estimating the time-varying expected shortfall associated with the EWQR quantile forecast. We express EWQR in a kernel estimation framework, and then modify it by adapting a … WebFeb 10, 2016 · You can compute a variable timeElapsed = modelingTime - observationTime. Now you apply a simple exponential function as W=K*exp (-timeElapsed/T), where K is a scaling constant and T is the time-constant for the decay function. W works as case-weight.
