+### Usage
+
+```c
+#include "stdlib/stats/base/dists/erlang/kurtosis.h"
+```
+
+#### stdlib_base_dists_erlang_kurtosis( k, lambda )
+
+Evaluates the excess kurtosis for a erlang distribution with shape parameter `k` and rate parameter `lambda` at a value `x`.
+
+```c
+double y = stdlib_base_dists_erlang_kurtosis( 1.0, 1.0 );
+// returns ~6.0
+
+y = stdlib_base_dists_erlang_kurtosis( 4.0, 12.0 );
+// returns ~1.5
+
+y = stdlib_base_dists_erlang_kurtosis( 8.0, 2.0 );
+// returns ~0.75
+
+y = stdlib_base_dists_erlang_kurtosis( 1.0, -0.1 );
+// returns NaN
+
+y = stdlib_base_dists_erlang_kurtosis( -0.1, 1.0 );
+// returns NaN
+
+y = stdlib_base_dists_erlang_kurtosis( 2.0, NaN );
+// returns NaN
+
+y = stdlib_base_dists_erlang_kurtosis( NaN, 2.0 );
+// returns NaN
+```
+
+The function accepts the following arguments:
+
+-   **k**:      `[in] double` shape parameter
+-   **lambda**: `[in] double` rate parameter
+
+```c
+double stdlib_base_dists_erlang_kurtosis( const double k, const double lambda );
