+# Entropy
+
+> [Hypergeometric][hypergeometric-distribution] distribution [entropy][entropy].
+
+The [entropy][entropy] (in nats) for a [hypergeometric][hypergeometric-distribution] random variable is
+
+
+
+
+
+
+where `N` is the population size, `K` is the subpopulation size, and `n` is the number of draws.
+
+
+
+## Usage
+
+```javascript
+var entropy = require( '@stdlib/stats/base/dists/hypergeometric/entropy' );
+```
+
+#### entropy( N, K, n )
+
+Returns the [entropy][entropy] of a [hypergeometric][hypergeometric-distribution] distribution with parameters `N` (population size), `K` (subpopulation size), and `n` (number of draws).
+
+```javascript
+var v = entropy( 16, 11, 4 );
+// returns ~1.216
+
+v = entropy( 2, 1, 1 );
+// returns ~0.693
+```
+
+If provided `NaN` for any parameter, the function returns `NaN`.
+
+```javascript
+var v = entropy( NaN, 10, 4 );
+// returns NaN
+
+v = entropy( 20, NaN, 4 );
+// returns NaN
+
+v = entropy( 20, 10, NaN );
+// returns NaN
+```
+
+If provided a parameter that is not a nonnegative integer, the function returns `NaN`.
+
+```javascript
+var v = entropy( 10.5, 5, 2 );
+// returns NaN
+
+v = entropy( 10, 1.5, 2 );
+// returns NaN
+
+v = entropy( 10, 5, -2.0 );
+// returns NaN
+```
+
+If the number of draws `n` exceeds the population size `N`, the function returns `NaN`.
+
+```javascript
+var v = entropy( 10, 5, 12 );
+// returns NaN
+```
+
+If the subpopulation size `K` exceeds the population size `N`, the function returns `NaN`.
+
+```javascript
+var v = entropy( 10, 12, 5 );
+// returns NaN
+```
+
+
+
+
+
+
+
+## Examples
+
+```javascript
+var entropy = require( '@stdlib/stats/base/dists/hypergeometric/entropy' );
+
+var v = entropy( 16, 11, 4 );
+console.log( v );
+// => 1.2156868611027067
+
+v = entropy( 2, 1, 1 );
+console.log( v );
+// => 0.6931471805599453
+
+v = entropy( 10, 5, 12 );
+console.log( v );
+// => NaN
+```

+{{alias}}( N, K, n )
+ Evaluates the entropy for a hypergeometric distribution with population
+ size `N`, subpopulation size `K`, and number of draws `n`.
+
+ If provided `NaN` as any argument, the function returns `NaN`.
+
+ If provided a population size `N`, subpopulation size `K` or draws `n` which
+ is not a nonnegative integer, the function returns `NaN`.
+
+ If the number of draws `n` or subpopulation size `K` exceeds population size

+
+ Parameters
+ ----------
+ N: integer

+ Number of draws.
+
+ Returns

+* Returns the entropy of a hypergeometric distribution.
+*
+* ## Notes
+*
+* - If provided a population size `N`, subpopulation size `K` or draws `n` which is not a nonnegative integer, the function returns `NaN`.
+* - If the number of draws `n` or subpopulation size `K` exceeds population size `N`, the function returns `NaN`.
+*
+* @param N - population size
+* @param K - subpopulation size
+* @param n - number of draws
+* @returns entropy
+*
+* @example
+* var v = entropy( 16, 11, 4 );
+* // returns 1.2156868611027067
+*
+* @example
+* var v = entropy( 2, 1, 1 );
+* // returns 0.6931471805599453

+* @example
+* var v = entropy( 10, 5, 12 );
+* // returns NaN
+*
+* @example
+* var v = entropy( 10.3, 10, 4 );
