And you have not yet said what that error is. In fact you flatly refused to on several occasions. The supposed error does not in fact exist.
You were right when you said that the artificial situation of just two accounts exaggerated the effect; That doesn't mean there was an error -- the bias unquestionably exists.
Nope, sorry. Remember, You flatly refused to explain. You don't get to flatly refuse to explain, and then claim that you did.
The model is correct; The only question is, does it matter? And the answer given the broader simulation above is, probably not. With many accounts no one having more than a small fraction of the total money, the bias is very small. But it definitely does exist.
The error I'm talking about is an attempt to model forging with 2 accounts only.
Bias does exist, I was always saying this when discussed with other guys who asked the same questions. But it's very small to pay attention, close to dispersion (subject to account balances). I refused to explain coz practice proves my position and it's YOU who is supposed to prove that ur model is correct.
