+### Usage
+
+```c
+#include "stdlib/stats/base/dists/bernoulli/mgf.h"
+```
+
+#### stdlib_base_dists_bernoulli_mgf( t, p )
+
+Evaluates the moment-generating function ([MGF][mgf]) of a [Bernoulli][bernoulli-distribution] distribution with success probability `p`.
+
+```c
+double y = stdlib_base_dists_bernoulli_mgf( 0.2, 0.5 );
+// returns ~1.111
+```
+
+The function accepts the following arguments:
+
+-   **t**: `[in] double` input value.
+-   **p**: `[in] double` success probability.
+
+```c
+double stdlib_base_dists_bernoulli_mgf( const double t, const double p );
