How do I calculate a12 and a21 for Lotka Volterra Competition model?

17 December 2022 0 7K Report

Hi,

I see papers on the Lotka-Volterra competition model in R and the authors have their a12 and a21 values set in the model. However, I am unclear on how they got to that value. Is it derived from the formula 0 = K1 - N1 - a12N2 and 0 = K2 - N2 -a21N1 or there is another formula I could calculate it for my species? Any help will be appreciated.

Thank you.
