# scipy.stats.itemfreq

scipy.stats.itemfreq(*args, **kwds)

  `itemfreq` is deprecated! `itemfreq` is deprecated and will be removed in a future version. Use instead np.unique(…, return_counts=True)

  Return a 2-D array of item frequencies.

  Parameters
    a(N,) array_like

      Input array.

  Returns
    itemfreq(K, 2) ndarray

      A 2-D frequency table. Column 1 contains sorted, unique values from a, column 2 contains their respective counts.

  Examples

      >>> from scipy import stats
      >>> a = np.array([1, 1, 5, 0, 1, 2, 2, 0, 1, 4])
      >>> stats.itemfreq(a)
      array([[ 0.,  2.],
             [ 1.,  4.],
             [ 2.,  2.],
             [ 4.,  1.],
             [ 5.,  1.]])
      >>> np.bincount(a)
      array([2, 4, 2, 0, 1, 1])

      >>> stats.itemfreq(a/10.)
      array([[ 0. ,  2. ],
             [ 0.1,  4. ],
             [ 0.2,  2. ],
             [ 0.4,  1. ],
             [ 0.5,  1. ]])
