Hi,
I found some comments which are not implemented.
As far as I have examined, these comments refer to min_group_size,
but min_group_size was decided not to adopt and removed[1], so
it seems these comments also should be removed.

Hi,
I found below formula to compute selectivities, but

Hi,
I found below formula to compute selectivities, but
I think the last Probability 'P(b=?)' should be 'P(c=?)'.
P(a=?,b=?,c=?) = P(a=?,b=?) * (d + (1-d)*P(b=?))
Attached patch fixes it, and it also adds some spaces
following another formula which is on line 86 and
computes P(a=?, b=?).
