Fig. 6: The stages of the spatial diffusion and the scale growth of COVID-19.

Note: This is a study on spatial multifractal patterns. Due to the analyses are made on the multifractal patterns of 42 consecutive days, the fractal parameters form a set of sample paths. A sample path is a subset of time series, representing a section taken from a time series. Time series is a theoretical concept, and empirical analysis focuses on sample paths.
