If rate of P (r for short) is within the interval [r1, r2] with 90% certainly:
Assuming that X obeys stand logistic distribution, so the possibility that X is in [-2.94443897916644,
2.94443897916644] equals 0.9. The standard deviation of F is pi/sqrt(3)*gamma where gamma is shape
parameter. Assuming variance of r equals expectation mu, we have sqrt(mu) = pi/sqrt(3)*gamma. And x =
parameter. Assuming variance of r equals expectation mu, we have sqrt(mu) = pi/sqrt(3)*gamma. And x =
(r - mu) / gamma, so r = x * gamma + mu. Instead x with ±2.94443897916644, gamma = sqrt(3*mu)/pi, we get
r = ±2.94443897916644 * sqrt(3*mu) / pi + mu = 1.623354290020702 * sqrt(mu) + mu.
