When your data (your mobility table) are available as a Stata matrix as
suggested by Nick Cox, it is straightforward to compute standard mobility

A couple of examples:

/* Shorrocks' MET - Prais Index */

loc q = rowsof(`M')
loc tr = trace(`M')
loc MET = (`q' - `tr')/(`q'-1)
di in gr "  Shorrocks' MET - the Prais index" _col(38) ": " %5.3f in ye

/* The Determinant Index */
loc det = det(`M')
loc DETI = 1 - (abs(`det'))^(1/(`q'-1))
di in gr "  Determinant Index " _col(38) ": " %5.3f in ye `DETI'
