Hi, this is probably simple for most but I'm a little puzzled.
Say I have a recurrence system
P_n+1 - P_n=(0.45 + 0.005P_n)P_n (n=0,1,2,3....)
and I want to put it in logistic form
rP_n(1 - P_n/E)
where r and E are positive parameters
Both examples I have are of the form (a - bP_n)P_n which means I get the 1 -, but now my logistic form is going to be 1 +, does this matter??
Apologies if this is the wrong forum but it seemed quite general.
Also sorry if this is a boneheaded question.
