Logistic Command

Logistic( <Mean>, <Scale>, <Variable Value> ): Evaluates the cumulative distribution function of a logistic distribution at variable value v, i.e. calculates the probability P(X ≤ v) where X is a random variable with a logistic distribution defined by the given parameters mean and scale.

This syntax returns the probability at a given value, that is the area under the logistic distribution curve to the left of the given x-coordinate.

Logistic( <Mean>, <Scale>, <Variable Value>, <Boolean Cumulative> ): If Cumulative = true, evaluates the cumulative distribution function of a logistic distribution with given mean and scale at the given variable value, otherwise it evaluates the probability density function of the distribution at variable value.
Logistic( <Mean>, <Scale>, x, <Boolean Cumulative> ): If Cumulative = true, creates the cumulative density function (cdf) of a logistic distribution with given mean and scale, otherwise it creates the probability density function (pdf) of the distribution.
