Figure 1
The figure contains two timelines, represented by horizontal arrows arranged vertically. The top and bottom timelines are labeled “Weekly Rolling Forecast, Round 1” and “Weekly Rolling Forecast, Round 2,” respectively, on the left side. Each timeline includes labeled vertical lines and text boxes. The details of each timeline are as follows: First timeline (Top): The first vertical line is positioned at one-eighth of the length of the horizontal arrow. A box is placed below the line, labeled “Estimation Period Begins.” The second vertical line is positioned at three-eighths of the length of the horizontal arrow. A box is placed below the line, labeled “Estimation Period Ends.” The third vertical line is positioned slightly to the right of the mid-point of the length of the horizontal arrow. A box is placed below the line, labeled “Forecast Begins.” The fourth vertical line is positioned at three-fourths of the length of the horizontal arrow. A box is placed below the line, labeled “Forecast Ends.” The second and the third lines combine at the top by a horizontal curly bracket, with the ends of the bracket extending towards the second and the third line. The text “Forecast Lag” is written above the center of the bracket. The line between the second and the third box is shown as a dotted line. The text “1 Week” is shown between the third and the fourth line, above the line. It is closer to the third box. Second timeline (Bottom): The first vertical line is positioned at one-eighth of the length of the horizontal arrow. A box is placed below the line, labeled “Estimation Period Begins.” A second short dotted vertical line appears at three-eighths of the arrow’s length, with a faded box below labeled “Previous Estimation Period Ends.” The third solid vertical line is positioned at the midpoint of the length of the horizontal arrow. A box is placed below this line, labeled “Estimation Period Ends.” The fourth vertical line is positioned at three-fourths of the length of the horizontal arrow. A box is placed below the line, labeled “Forecast Begins.” The fifth vertical line is positioned at seven-eighths of the arrow’s length. A box is placed below the line, labeled “Forecast Ends.” The third and fourth solid lines are joined at the top by a horizontal curly bracket, with the ends of the bracket extending towards the third and fourth lines. The text “Forecast Lag” is written above the center of the bracket. The text “1 Week” is placed between the faded second and the third vertical line, and again between the fourth and the fifth solid lines. The line between the first and the second box is shown as a dotted line.Visualization of rolling forecasts. Source: Created by authors
