scipy.stats.find_repeats

scipy.stats.find_repeats(arr)

Find repeats and repeat counts.

Parameters:

arrarray_like

Input array. This is cast to float64.

Returns:

valuesndarray

The unique values from the (flattened) input that are repeated.

countsndarray

Number of times the corresponding ‘value’ is repeated.

Notes

In numpy >= 1.9 numpy.unique provides similar functionality. The main difference is that find_repeats only returns repeated values.

Examples

>>> from scipy import stats
>>> stats.find_repeats([2, 1, 2, 3, 2, 2, 5])
RepeatedResults(values=array([2.]), counts=array([4]))

>>> stats.find_repeats([[10, 20, 1, 2], [5, 5, 4, 4]])
RepeatedResults(values=array([4.,  5.]), counts=array([2, 2]))
