Empirical results can be very dependent on model specification. How can analysts show model robustness in their research?

OR: Paste the following command into STATA:
The multi-model analysis framework allows researchers to
(1) estimate thousands of regression models across combinations of control variables, functional forms, alternative variable definitions, and estimation commands;
(2) display the resulting modeling distribution of estimates; and
(3) discover which aspects of model specification have the most influence on a parameter estimate.
This allows analysts to clarify and demonstrate which modeling assumptions are essential to their empirical findings, and which are not.
This is part of an enduring theme in my research, focusing on robust results. My earlier research:
