I try to run a 'ivreg' command in R in my desktop PC. However, when I run this code, it does not response permanently which I usually expect the results to come out in a second.
I try this same 'ivreg' command in my other laptop PC (which is much less compatible than my desktop PC) then the result comes out in a second.
I was using the exactly same code sheet and data but simply on a different computer, but one works (laptop PC with much weaker performance) and the other one (desktpo PC with much stronger performance) does not.
Strangely, all other codes work normally on both PCs but not only this code. Both PCs have this 'ivreg' related package (AER) installed properly.
May I get help on this please?
