Day-ahead vs 2Day_ahead? #20

Open williamhobbs opened 1 year ago

williamhobbs commented 1 year ago

Here you describe day-ahead, intra-day, and intra-hour forecasts, but it seems like the "day-ahead" forecast may be represented in the dataset at Day-ahead and 2Day_ahead (e.g., for solar in ERCOT, 2Day_ahead and Day-ahead.

This would make sense, as this,

Day-ahead forecasts are generated with a 11-hour-ahead lead time, a 48-hour horizon, an hourly resolution, and a daily update rate

results in overlapping time series, where there are more than one forecasted value each forecast time.

Can you clarify this? Thanks!

For context, this came up when I was looking at this question, https://stats.stackexchange.com/questions/586078/what-does-this-statement-about-a-forecasting-lead-time-mean/.

You are correct about the day-ahead being represented by both the Day-ahead and 2Day_ahead datasets, with the latter represented the forecast 2 days out. @fzhang-WZ or @fengcong1992 might be able to provide more details if needed.
