Dear Statalist subscribers,

Thanks to Professor Baum, a new package -isa- is now available 
from SSC. 
-isa- automatically produces a figure for the sensitivity 
analysis developed by Imbens (2003). Please refer to his 
"Sensitivity to Exogeneity Assumptions in Program Evaluation." 
AER 93(2):126-132, for technical detail.

My only precaution is that finding good initial values of 
alpha and delta requires many trials for unbalanced data.

I plan to release -gsa-, the computational version of -isa-, 
that can deal with continuous treatment variable. Any 
interested persons are welcomed to contact me.
