I am studying a code of a paper which I will use for my own research. In this code I saw that the authors did not use the “=” symbol for explaining their equations but rather used a “-”. Example:
SDF - (betaH*uc(+1))/uc;
SDF = (betaH*uc(+1))/uc;
with SDF as stochastic discount factor.
Is there any difference between these two types? When I changed some equations in my own model, it still generated output but somehow the numbers of the IRFs were different.
