skbio.diversity.alpha.lladser_pe

skbio.diversity.alpha.lladser_pe(counts, r=10)

Calculate single point estimate of conditional uncovered probability.

Parameters:

counts1-D array_like, int

Vector of counts.

rint, optional

Number of new colors that are required for the next prediction.

Returns:

double

Single point estimate of the conditional uncovered probability. May be np.nan if a point estimate could not be computed.

Notes

This function is just a wrapper around the full point estimator described in Theorem 2 (i) in [1], intended to be called for a single best estimate on a complete sample. This function is not guaranteed to return estimated uncovered probabilities less than 1 if the coverage is too low.
