+
+```c
+#include "stdlib/stats/base/dists/lognorma/pdf.h"
+```
+
+#### stdlib_base_dists_lognormal_pdf( x, a, b, c )
+
+Evaluates the [probability density function][pdf] (PDF) of a [lognormal][lognormal-distribution] distribution with parameters input value `x`, location parameter `mu` and scale parameter `sigma`.
+
+```c
+double y = stdlib_base_dists_lognormal_pdf( 2.0, 0.0, 1.0 );
+// returns ~0.157
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] double` input value.
+-   **mu**: `[in] double` location parameter.
+-   **sigma**: `[in] double` scale parameter.
+
+```c
