+### Usage
+
+```c
+#include "stdlib/math/base/special/boxcoxinv.h"
+```
+
+#### stdlib_base_boxcoxinv( y, lambda )
+
+Computes the inverse of a one-parameter [Box-Cox transformation][box-cox-transformation].
+
+```c
+double out = stdlib_base_boxcoxinv( 1.0, 2.5 );
+// returns ~1.6505
+
+out = stdlib_base_boxcoxinv( 4.0, 2.5 );
+// returns ~2.6095
+```
+
+The function accepts the following arguments:
+
+-   **y**: `[in] double` input value.
+-   **lambda**: `[in] double` power parameter.
+
+```c
+double stdlib_base_boxcoxinv ( const double y, const double lambda );
