Logistic Command

Logistic( <Mean>, <Scale>, x ): Creates cumulative density function (cdf) of logistic distribution with parameters mean μ and scale s.
Logistic( <Mean>, <Scale>, x, <Boolean Cumulative> ): If Cumulative is true, creates cumulative distribution function of logistic distribution, otherwise creates pdf of logistic distribution.
Logistic( <Mean>, <Scale>, <Variable Value> ): Calculates the value of cumulative distribution function of logistic distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with logistic distribution given by parameters mean μ and scale s.

Returns the probability for a given x-coordinate’s value (or area under the logistic distribution curve to the left of the given x-coordinate).
