The -somersd- package, downloadable from SSC, measures stochastic
dominance, using confidence intervals for Somers' D or Harrell's c
index. It has m.pdf manuals, which explain the theory.
I hope this helps.
Best wishes

Subject: st: About stochastic dominance analysis??
Dear statalists,
I have two groups of farm households in my data, say Group A and Group
B. Group A used soil conservation measures while Group B did not. I have
data on yield (total value product per unit area) for each groups. I
used kdensity to examine whether yields on conserved plots dominates the
yield on non-conserved ones. However, the kdensity graphs are crossing
each other at some points and therefore, difficult to conclude.
Is there any way to do it?
regards
