# Logistic

Logistic distribution.

## Usage

```
var logistic = require( '@stdlib/stats/base/dists/logistic' );
```

#### logistic

Logistic distribution.

```
var dist = logistic;
// returns {...}
```

The namespace contains the following distribution functions:

`cdf( x, mu, s )`

: logistic distribution cumulative distribution function.`logcdf( x, mu, s )`

: logistic distribution logarithm of cumulative distribution function.`logpdf( x, mu, s )`

: logistic distribution logarithm of probability density function (PDF).`mgf( t, mu, s )`

: logistic distribution moment-generating function (MGF).`pdf( x, mu, s )`

: logistic distribution probability density function (PDF).`quantile( p, mu, s )`

: logistic distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

`entropy( mu, s )`

: logistic distribution differential entropy.`kurtosis( mu, s )`

: logistic distribution excess kurtosis.`mean( mu, s )`

: logistic distribution expected value.`median( mu, s )`

: logistic distribution median.`mode( mu, s )`

: logistic distribution mode.`skewness( mu, s )`

: logistic distribution skewness.`stdev( mu, s )`

: logistic distribution standard deviation.`variance( mu, s )`

: logistic distribution variance.

The namespace contains a constructor function for creating a logistic distribution object.

`Logistic( [mu, s] )`

: logistic distribution constructor.

```
var Logistic = require( '@stdlib/stats/base/dists/logistic' ).Logistic;
var dist = new Logistic( 2.0, 4.0 );
var y = dist.pdf( 2.0 );
// returns 0.0625
```

## Examples

```
var objectKeys = require( '@stdlib/utils/keys' );
var logistic = require( '@stdlib/stats/base/dists/logistic' );
console.log( objectKeys( logistic ) );
```
