The floor value for clipping in SamplingProbablityCorrection could be too high for larger datasets

Hi,

The current value of 1e-6 is set here. The rationale seems to be to avoid zeros but the value set could be too high for larger datasets and result in lower metrics on a private dataset. This stops us from updating the package to versions >0.6.0. What would be the best way to address it?

One way could be to set a lower value as suggested here. Also, there seems to be a typo in the naming of the class that's already addressed in another PR that hasn't been merged yet
