From b2f4b559a3bc69c384f6c83ee7d8efca7712adc8 Mon Sep 17 00:00:00 2001 From: Sitsofe Wheeler Date: Wed, 28 Jun 2017 22:30:24 +0100 Subject: [PATCH] doc: fix random_distribution Gaussian parameter name random_distribution's parameter for a Gaussian distribution is called "normal". Note this differs to file_service_type where the Gaussian distribution really is selected with the "gauss" parameter.
