Re: st: how to use inverse hyperbolic sine function
An inverse hyperbolic sine transformation is:
IHS = log(z + sqrt(z^z + 1))
It is an alternative to log transformations when some of
the variables take on zero or negative values and as
an alternative to the Box-Cox when variables are zero or
See, for example:
