Reorder point (inventory) as quantile estimation of the demand[edit]

The article does not discuss much about the practical application of quantiles. For retail and manufacturing, quantile regression is very handy for inventory management because it basically represents the reorder point in an inventory optimization context, see http://www.lokad.com/reorder-point-definition.ashx Disclaimer: I am a shareholder of Lokad, and might have a biased POV (so I prefer to let someone else deal with this part of the discussion on the primary article). --Joannes Vermorel (talk) 15:23, 23 February 2012 (UTC)

In the intuition section, I think the amount of change in the expected loss due to the shift of q by 1 is wrong. I get 0.5 times the integral of the density from negative infinity to q, minus 0.5 times the integral of the density from q to infinity, plus the integral of y-q-1 times the density from q to q+1. Even if what is written on the article now is correct, some explanation would be appreciated. Tet21tet (talk) 06:03, 27 May 2014 (UTC)
