Want to do many regressions using ivreg2 with different variables and add them all to the results table

[Mustapha Younis]

Want to do many regressions using ivreg2 with different variables and add them all to the results table. For example regression (1) for a certain variable, regression (2) another variable, etc....... and then save all these regressions in one results table showing all the results of the previous regressions. Thanks.
