+### Usage
+
+```c
+#include "stdlib/stats/base/dists/triangular/kurtosis.h"
+```
+
+#### stdlib_base_dists_triangular_kurtosis( a, b, c )
+
+Returns the [excess kurtosis][kurtosis] of a [triangular][triangular-distribution] distribution with minimum support `a`, maximum support`b`, and mode `c`.
+
+```c
+double out = stdlib_base_dists_triangular_kurtosis( 0.0, 1.0, 0.8 );
+// returns -0.6
+```
+
+The function accepts the following arguments:
+
+-   **a**: `[in] double` minimum support.
+-   **b**: `[in] double` maximum support.
+-   **c**: `[in] double` mode.
+
+```c
