Syntax ------
extrans variable(s)
The extrans command shows the effects of square root, log, and -1/square root transformation on the values of Q1, Q2, Q3 and (Q3-Q2)/(Q2-Q1). When a distribution is symmetric, the value of (Q3-Q2)/(Q2-Q1) should be 1. You can examine how these transformations influence the symmetry of the distribution using this meeasure.
