check_counts_validity(X, delta=0.0001, head=1000, raise_exception=True)

Checks whether matrix looks like it is a unnormalized uncentered count matrix

Parameters:

• X – Dense or sparse counts matrix.

• delta – The maximum absolute deviation from integer numbers to tolerate.

• head – The number of sored values of the count matrix to check for dviation from integer numbers.
