bincount will raise exception if data cannot be converted to integer.
- Parameters:
- dataarray_like, 2-Dim
data containing category assignment with subjects in rows and raters in columns.
- n_cat
None
orint
If None, then the data is converted to integer categories, 0,1,2,…,n_cat-1. Because of the relabeling only category levels with non-zero counts are included. If this is an integer, then the category levels in the data are already assumed to be in integers, 0,1,2,…,n_cat-1. In this case, the returned array may contain columns with zero count, if no subject has been categorized with this level.
- Returns:
- arr
