My first entry. Hope it's helpful, I am just feeling my way around here. —Preceding unsigned comment added by Plf515 (talkcontribs) 17:13, 24 November 2006

A good start, though IMHO the title should be consistent with that of the article Winsorising. Not that I necessarily prefer 'winsorised mean', I just think it is important to be consistent. Btyner (talk) 21:38, 30 December 2007 (UTC)[reply]
I would like to see information in advantages/disadvantages, compared to trimmed-mean —Preceding unsigned comment added by 203.206.162.148 (talk) 05:27, 23 September 2010 (UTC)[reply]

Percentage

I always thought that the example shows a 20% winsorized, as 2 out of 10 are replaced. Nijdam (talk) 18:15, 27 August 2011 (UTC)[reply]

Contradictory

"It involves the calculation of the mean after replacing given parts [...], typically discarding an equal amount of both [...]". Make up your mind: are you replacing (cardinality unchanged) or discarding (cardinality decreased)? Urhixidur (talk) 22:14, 2 March 2012 (UTC)[reply]

Some individual values are discarded AND replaced by different values, so no real error, but it could be rephrased. Melcombe (talk) 22:46, 2 March 2012 (UTC)[reply]
My point exactly. Thanks for fixing this. Urhixidur (talk) 19:49, 12 March 2012 (UTC)[reply]

Probability distribution

I never heard of the winsorised mean for a probability distribution. Nijdam (talk) 08:43, 25 June 2012 (UTC)[reply]

A simple search found this, http://books.google.co.uk/books?id=8f8nBb4__EYC&pg=PA30&dq=%22winsorized+distribution%22&hl=en&sa=X&ei=STnoT-foPITK0QWw9s2uCQ&ved=0CDsQ6AEwAA#v=onepage&q=%22winsorized%20distribution%22&f=false , which is definitely working with a theoretial distribution. The book is Introduction to Robust Estimation and Hypothesis Testing by Rand R. Wilcox. I guess there must be similar stuff elsewhere. Melcombe (talk) 10:17, 25 June 2012 (UTC)[reply]

The example is a bit confusing

The example wasn't really helpful to me. Are we dividing by 10 because the sample count is 10, or because we're taking the 10% Winsorized mean? (which looks rather like 20% (as someone pointed out earlier)).. Ai.unit (talk) 10:00, 25 June 2015 (UTC)[reply]
