Re: Units do not match
Fist thing, δx should have units of DMNL/month as it's a rate of change. I cannot really offer any more assistance as the model is not documented, I've got no idea what things like "L1" are (or if the units for it are even correct). When I simulate, there will be a variable out of range f...

Re: Units do not match
Units should always be very straightforward. Always enter what the parameter would be measured in in the real world. Can you upload the model? It's difficult to offer advice with so little to work on. I'd suggest that the probability is correct, that should be dimensionless. Cannot really offer any...

Re: Units do not match
Thank you for your help. I want to set the rate(variable)'s unit in eqution: dx/dt=x'(t)=a×x(t),a is const. But, units do not match(left and right hand). x(t) represent the probability of selecting one strategy, i set the unit: Dmnl, but the unit of [dx/dt] must be the 1/Month(or other time type), s...

Re: Units do not match
Thank you for your reply.
I have been uploaded the model.
The unit "CNY" is the chinese currency unit.

Units do not match
Right hand and left hand unit of replicator dynamics equation do not match
replicator dynamic equation:dy/dt=y(1-y)(URC-URN)
The left hand:percent/Month
The right hand:CNY
Although Units equivalents [percent/Month,CNY] were set, this problem still exist.
