Can someone who has the old Stata 7 message me and run a very short do file?

[Ching Wu]

I am trying to replicate data in a paper, and the results I got was different from the data in the paper in a special way that they were all powers of 2, e.g. 64, 2048, 8.
I suspect this happens due to the fact that data in the paper was generated using Stata 7.
Can someone who has Stata 7 message me and run the do-file for me to make sure?
Thanks!

Stata 7 is pretty old. It was released in 2000. It may even be old enough that it won't run on contemporary hardware, I don't know. If there are any copies still floating around, this Forum is probably the best place to look for them.

That said, have you tried running the do-file on your current Stata using version control?

[Ching Wu]

I didn’t know version control was a thing. I’ll give it a try. Thank you!

FWIW, I used Stata 7 when it was a thing. If anything produced only powers of 2 in Stata 7, I would lay overwhelming odds on it resulting from the user's code, not from a limitation or bug in Stata 7. So, I don't think it's Stata 7 you need. It's to show us the do-file.

Actually its not that my do file only produced powers of 2.
Let's say that the author of a paper made original.do and originaloutput.dta available on the internet and I downloaded them.
"originaloutput.dta" contains the output variable "output_variable_original".
And the author said original.do produces originaloutput.dta.
But once I run original.do, and let's say I chose the name myoutput.dta,
which contains the output variable "output_variable_my",
the differences between "output_variable_original" and "output_variable_my" are all powers of 2 like 0.25, 0.5, 1, 2, 4, 8, 16, etc.

Put yourself in our position. All we know is that there is some unspecified code and some unspecified dataset and the result of the code does not match the dataset. I would love to have magical abilities that would enable me to find the problem with just that information, but unfortunately I was only trained at a university and not at Hogwarts. In short, without the code and the data, there is nothing we can do.
