Ralf, thank you for this video, it's amazing. Can you recommend a paper to read (and cite) on this models?

thanks, this was useful for solving Hamilton exercise 3.3. The derivation of MA(inf) coefficients by AR(p) is done by taking A=(1-a1*L-...-ap*L^p) and inverting it giving A^-1=B(L) = (b0+b1*L+...). Then equate A*B(L)=1. Expand left hand side and group by all powers of L and setup a system of equations. Set first equation with L^0 to one, rest to zero. Solve all equations for b coefficients recursively.

Thanks for the clear (and very helpful) explanation! Would you mind indicating in which literature (if any) we can find the terms 'restricted' and 'unrestricted' as you referred to the models? Thanx again!
@HernanO3 ай бұрын
Great explanation, thank you so much. Did you use logy as the dependent variable to, then, be able to estimate odds ratios from the coefficients?

Hello sir, your videos are very insightful, thank you for taking the time. I see you explained how to run diff n diff in r. Please can do you have or know of resources that showed in detail with examples how to run fixed effect, instrumental variables, regression discontinuity and basically all the econometric models in R language.

Of course these LLMs won't give you precise information since they don't have access to the internet ─ they are just relying on internal memory. This test would be much more meaningful if you had used Bing Chat, which is based on GPT-4 and does indeed have access to the internet.
