Log-linear GDP Interpolation

[lrennels]

@bryanparthum as you brought up, perhaps this should be log-linear, I am discussing with @bprest now

[bryanparthum]

Thanks. I attempted it here last week but I don't know enough about LinearInterpolation to do it right and I think it's off. In addition to needing to improve my understanding of workflow for testing modifications across packages :-)

@bryanparthum oh nice I think this is actually correct, I'll double check this afternoon though. To test modifications across packages you can dev multiple into your environment, but I'm with you that that can get confusing because it means you have to manually make sure multiple packages are on the right version at once so I avoid it (@davidanthoff devs a bunch at a time but he's a pro).

Can you make that a PR on this package? Turns out I can edit your forks with the VSCode extension so I can double check it and then do the version control updating and have it to you by this afternoon.

[bryanparthum]

Sure thing. Okay great, I was just deving both, so if that's how it supposed to be done then that's reassuring.

[lrennels]

Yep that should work! Once we merge this you can un-dev

Closing! Done!
