Struct ndarray_stats::histogram::strategies::Rice
source · pub struct Rice<T> { /* private fields */ }Expand description
A strategy that does not take variability into account, only data size. Commonly overestimates number of bins required.
Let n be the number of observations and n_bins the number of bins.
n_bins = 2n1/3
n_bins is only proportional to cube root of n. It tends to overestimate
the n_bins and it does not take into account data variability.
