Food insecurity is characterized by low predictability. The average predictability \(\chi = 1-H\) for daily trends of insufficient food consumption, in the six analyzed countries, is shown as a function of time series length in days. We average H over temporal windows by selecting 1000 random points from each time series and calculating H for windows of length 10, 11, 12, ..., 100 days. The solid lines indicate the mean value and the shaded areas mark the interquartile range across all administrative units and starting locations in the time series.
