After splitting my data as the "in and out-of-sample" for volatility forecasting purpose in R, I estimate HAR model, but my estimated HAR model is for the whole sample. It does not estimate for the in sample. is there any specific code to include only in-sample?

  • $\begingroup$ i just found the code: HARestimate(vRealizedMeasure = rv5_SPX[1:1917], vLags = c(1,5,22)) just need to specify time interval after your variable as above $\endgroup$ – barr Aug 8 at 14:32
