Hi all, I am trying to represent this mathematical expression into a SD-Vensim model: X(t)=∫X(t,r)f(r)dr The integral is defined between zero and R=2 (for example) X(t,r) represent a variable (disease incidence) at time t with a rate r, and is defined by the logistic equation X(t)=1/(1+(1-Yo/Yo)*EX...

By multiplying the right-hand side of the equation by this conversion factor, you can ensure that the units match. The modified equation would then be:

dy/dt = y(1-y) * conversion_factor * (URC - URN)
