* Implement in-space placebo test using fake treatment units with pre-treatment MSPE 2 times smaller than or equal to that of the treated unit
* For illustration, we drop the "allopt" option to save time. The "allopt" option is recommended for the most accurate results if time permits.
* To assure convergence, we change the default option "sigf(7)" (7 significant figures) to "sigf(6)".
