Figure 2.
The time series chart depicts trend prediction through time series analysis. The x-axis shows Year, and the y-axis shows Frequency. A historical frequency line remains low from the early years, then increases gradually after 2000 and rises sharply in recent years. On the right side, forecasted trend bands illustrate three categories. Hot Fields show a steep upward trajectory with widening forecast uncertainty. Active Fields show a moderate upward trend with relatively stable frequency levels. Cold Fields show a declining trend with decreasing frequency over time. Shaded forecast intervals represent uncertainty around the predicted trends, illustrating distinct growth behaviours across field categories.Example of time-series (ARIMA) analysis
