We use simulated historical forecasts (SHFs) by producing K forecasts at various cutoff points in the history, chosen such that the horizons lie within the history and the total error can be evaluated.
This sentence is very difficult to understand
chosen such, choose the horizon or the history, why use the past participle of choose ?
- I can understand such horizons, that horizons, the horizons, they are same. But what is
such that the horizons??? I know sentence like
we could eat this such that we don't go hungry, but here it doesn't look like, because there is a
such thatwhich doesn't relate to previous sentence.
lie within the history, why use within here ?
Actually I don't understand what
horizonsstands for at here. I only know the meanings as below
the place in the distance where the earth and sky seem to meet: [ U ] We watched the horizon as the sun set. A person’s horizons are the limit of that person’s ideas, knowledge, and experience: [ pl ] Spending her junior year abroad has broadened her horizons.
