Ghosh implementation for downstream scope 3

[Beckebanze]

See issue #135 for more details.

With this PR the following is added/implemented:

• equivalent of A for Ghosh (often referred to A* in literature)
• the Ghosh inverse (often referred to G in literature). If the Leontief matrix L is already calculated, then G is calculated based on L because the calculation based on A* is computationally much more expensive.
• downstream scope 3 multiplier, M_{down}, such the sum of the M+M_{down} is the full scope multiplier, with M the existing multiplier in pymrio that covers scope 1,2&3 upstream.
• a short addition to the pymrio background page that introduces the Ghosh model
• tests that test the functionality of the added functions

Hi, there are some problems with pytest 8.*, can you change the line in the environment.yml file to
- pytest >= 5.4.3, < 5.8.0
and then push again to the pr

[Beckebanze]

Thanks. I updated the environment.yml.

So the test run now, just one small problem with the formating. When you run the format_and_test from the route within your environment it should just format everything as it should be. If you are not on linux, you can run the lines of the files from the cml in windows.

I run it locally, and then all your tests pass

[Beckebanze]

Indeed. iomath.py was not yet correctly formatted in this PR. It apparently slipped through when I committed all formatting changes to my development branch.

There is still some black problems, do you use the same version ( black 24.2.0 ).. See also the details of the run

@Beckebanze : let me know if there are any issues

[Beckebanze]

Hi Konstantin,I had an unusually busy two weeks at work and I’m on vacation for a few days as off today.I have the impression that the problem is all about version conflicts. I will pick up trying to understand which ‘black’ versions do work and which don’t after my vacation. Best,FelixOn 12 Mar 2024, at 10:11, Konstantin Stadler ***@***.***> wrote: @Beckebanze : let me know if there are any issues —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you were mentioned.Message ID: ***@***.***>

Hi,

If you go into the CI run you see a section "list environment".
There you find the versions of all packages used, for black:
black 24.2.0 py39hf3d152e_0 conda-forge

Your changes pass the tests on my local machine as well - so yes, I guess it is just some annoying version conflict.. I am kind of pushing you to do that via a pull request so you are listed as an official contributor.
But for now enjoy your holiday!

There are indeed changes due to the new version of black in files that I haven’t touched. I used black 24.3.0 for the committed changes. On 19 Mar 2024, at 09:18, Konstantin Stadler ***@***.***> wrote: Hi, If you go into the CI run you see a section "list environment".

Great, I will merge that for now, but we need some more documentation on the use

[konstantinstadler]

Fantastic to get that in!
