+### Usage
+
+```c
+#include "stdlib/stats/base/dists/chisquare/mgf.h"
+```
+
+#### stdlib_base_dists_chisquare_mgf( t, k )
+
+Evaluates the moment-generating function (MGF) for a chi-squared distribution with degrees of freedom `k` at a value `t`.
+
+```c
+double out = stdlib_base_dists_chisquare_mgf( 0.4, 2.0 );
+// returns ~5.0
+```
+
+The function accepts the following arguments:
+
+-   **t**: `[in] double` input value.
+-   **k**: `[in] double` degrees of freedom (must be non-negative).
+
+```c
+double stdlib_base_dists_chisquare_mgf( const double t, const double k );
+```
