The expected value of logistic distribution to the curve fitted are parametric; the mean (μ) are E (x) = μ and the standard variance (σ) of this distribution is Var(x) = , the distribution is symmetric [Paul et al., 1995]
o The tree structure of expected value using logistic distribution to the curve fitted are parametric; the mean (μ) are E (x) = μ and the standard variance (σ) of this distribution is Var(x) = , the distribution is symmetric [Paul et al., 1995].
