Correlations of waiting time (Δt), duration (T), and peak counts (P) across various energy bands. (a) Correlation between duration (T) and peak counts (P). (b) Correlation between duration (T) and waiting time (Δt). Solid lines (colored accordingly) represent the trend fits obtained using a simple power-law function. Spearman correlation coefficient and p-value are calculated to measure the relationship between two parameters, highlighted in corresponding colors in two panels. The Spearman coefficient measures the strength and direction of the monotonic association (ranging from −1 to 1, where values closer to −1 represent strong anticorrelation and values closer to 1 represent strong positive correlation), while the p-value indicates the significance of the correlation, with smaller p-values representing stronger significance.
