I am trying to estimate the 'Long Differences' regression to understand the impact of changing temperature on crops yield over 30 years.
I appreciate if someone can provide the proper estimation procedure in Stata or R software to conduct the regression.
This is a famous series of papers b y R.A. Fisher See: this list: https://www.google.com/search?client=firefox-b-1-d&q=Studies+in+Crop+Variation+rain+on+wheat+yield+at+Rothampsted
I believe the one you want is most likely III Then see this link:

Ok now google long distance regression and ask how does this topic relate to Fisher's data and what is a good way to find patterns in your data.? Of course I may be completely wrong but that is how research works. Good hunting. David Booth part 2
Finally, you might Google. Davidian, longitudinal model notes NCSU Statistics. This is where the code can often be found. Best of luck, David Booth
