Calculates the Sorensen index between two groups of repertoires. Similar to a Jaccard index, Sorensen index gives a greater weight to shared sequences over unique sequences.
Arguments
- sample_list
A list of two tibble corresponding derived from the
productiveSeq()function in LymphoSeq2. "duplicate_frequency", "junction_aa", and "repertoire_id" columns are necessary for the calculation of the Bhattacharyya coefficient.
Value
Returns the similarity score, a measure of the amount of overlap between two samples. The value ranges from 0 to 1 where 1 indicates the sequence frequencies are identical in the two samples and 0 indicates no shared frequencies.
