Dived a data set based on PS #58
Description
The example in the README.md is a bit overwhelming for me.
And I can not see where there a data set is divided based on the PS. In some cases you use the PS to dived a dataset (with control and treat group together). In the result you got two datasets one for control and one for treat but both of them of the same length.
I can not see this in your example.
