other methods of assessing lacunarity from box counting data use the relationship between values of lacunarity (e.g., formula_16) and formula_4 in different ways from the ones noted above. one such method looks at the formula_26 vs formula_26 plot of these values. according to this method, the curve itself can be analyzed visually, or the slope at formula_15 can be calculated from the formula_26 vs formula_26 regression line. because they tend to behave in certain ways for respectively mono-, multi-, and non-fractal patterns, formula_26 vs formula_26 lacunarity plots have been used to supplement methods of classifying such patterns.
