Witryna29 paź 2016 · In logistic regression, actually it is how logistic function is defined via the maximum entropy and lagrange multipliers, this constraint must be met with other two: E p f j = E p ^ f j. That is, the model's expectation should match the observed expectation, which has been illustrated in this paper. Witryna25 lip 2014 · In your example you have Nₒ=2, and a point in time t=2⨉10^5 and N(2⨉10^5) = 7⨉10^9, but you still lack the value of r to get the value of K. The equation solved for K is: Nₒ·e^(-rt) - N(t)
