# skbio.diversity.alpha.lladser_ci

`skbio.diversity.alpha.``lladser_ci`(counts, r, alpha=0.95, f=10, ci_type='ULCL')

  Calculate single CI of the conditional uncovered probability.

  State: Experimental as of 0.4.0.

  Parameters:

  - counts (1-D array_like, int) – Vector of counts.
  - r (int) – Number of new colors that are required for the next prediction.
  - alpha (float, optional) – Desired confidence level.
  - f (float, optional) – Ratio between upper and lower bound.
  - ci_type ({'ULCL', 'ULCU', 'U', 'L'}) – Type of confidence interval. If `'ULCL'`, upper and lower bounds with conservative lower bound. If `'ULCU'`, upper and lower bounds with conservative upper bound. If `'U'`, upper bound only, lower bound fixed to 0.0. If `'L'`, lower bound only, upper bound fixed to 1.0.

  Returns: | Confidence interval as `(lower_bound, upper_bound)`.
  Return type: | tuple

  Notes

  This function is just a wrapper around the full CI estimator described in Theorem 2 (iii) in [1], intended to be called for a single best CI estimate on a complete sample.
