# STransformPackage(R, UTSR, ULSR, UPSR)¶

A package to computes Taylor and Puiseux series of S-transforms.
of the distributions x if the mean is zero distributionBySTransform(x) returns the distribution with S-transform x.
freeMultiplicativeConvolution(x, y) returns the free multiplicative convolution of the distributions x and y.
STransform(x) returns the Taylor expansion the S-transform S(z) of the distribution x if the mean is nonzero.
STransform(x) returns the Puiseux expansion of the S-transform S(z) if the mean is zero.
STransform(x) returns the Puiseux expansion of the S-transform S(z).
