Quantlet: | VaRdiagplot | |
Description: | produces calibration and discrimination plots which verify validity of probability forecasts. |
Usage: | VaRdiagplot(int,sig,real,g) | |
Input: | ||
int | mx2 matrix containing intervals in the rows. | |
sig | nx1 vector of predicted standard deviations (assume normality) | |
real | nx1 vector of realizations. | |
g | scalar, number of grid points. |
library("VaR") x=read("kupfer") ; time series x=x[1:1001] y=diff(log(x)) ; returns sig=VaRest(y)[,2]/qfn(0.99) y=y[251:1000] VaRdiagplot((-0.01~0.01),sig,y,10)
