WebNov 11, 2014 · The correlation sum C ^ ( r) is defined as "the fraction of pairs whose distance is smaller than r ". It appears that in your code the value of the correlation sum is supposed to be stored in count and then ratio (2, ·) and r in epsilon and then ratio (1, ·). I can't identify any point where the count is transformed into a ratio though. In chaos theory, the correlation dimension (denoted by ν) is a measure of the dimensionality of the space occupied by a set of random points, often referred to as a type of fractal dimension. For example, if we have a set of random points on the real number line between 0 and 1, the correlation dimension will be ν … See more • Takens' theorem • Correlation integral • Recurrence quantification analysis • Approximate entropy See more 1. ^ Peter Grassberger and Itamar Procaccia (1983).
