# scipy.stats.qmc.update_discrepancy

scipy.stats.qmc.update_discrepancy(x_new, sample, initial_disc)

  Update the centered discrepancy with a new sample.

  Parameters
    x_new array_like (1, d)

      The new sample to add in sample.

    sample array_like (n, d)

      The initial sample.

    initial_disc float

      Centered discrepancy of the sample.

  Returns
    discrepancy float

      Centered discrepancy of the sample composed of x_new and sample.

  Examples

  We can also compute iteratively the discrepancy by using `iterative=True`.

      >>> from scipy.stats import qmc
      >>> space = np.array([[1, 3], [2, 6], [3, 2], [4, 5], [5, 1], [6, 4]])
      >>> l_bounds = [0.5, 0.5]
      >>> u_bounds = [6.5, 6.5]
      >>> space = qmc.scale(space, l_bounds, u_bounds, reverse=True)
      >>> disc_init = qmc.discrepancy(space[:-1], iterative=True)
      >>> disc_init
      0.04769081147119336
      >>> qmc.update_discrepancy(space[-1], space[:-1], disc_init)
      0.008142039609053513
