This function calculates the edge-wise partial correlation difference for a single bootstrap.
single.boot(i, z, n, tY.org, P, levels.z, w.upper)iteration number. This is not used within this function, but necessary for parSapply within scoring.boot.parallel function.
a length n vector representing a binary covariate
the number of rows in data
