Here I found about Geometric median. But i am still unable to calculate Geometric median of some points (x, y)
. Can some body please calculate Geometric median by giving an example? For an example, let say i have six points a(-3,0), b(-2,0), c(-1,0), d(0,0), e(10,0), f(50,0)
. So what is the Geometric median of these points? Thank you.

2Did you try out the computation algorithm described in the wikipedia article you referred to? – 2012-04-15

0@HaraldHanche-Olsen: [Here](http://en.wikipedia.org/wiki/Geometric_median#Definition) is the Definition of Geometric median. I didn't get the formula. – 2012-04-15

0Harald is pointing out that the Computation paragraph of the Wikipedia essay seems to answer your question. What part of the discussion there are you finding difficult? – 2012-04-15

0@GerryMyerson: Okay.... actually i was concentrating on _Definition_ paragraph. – 2012-04-15
-
0Huh? Your question is about *calculating* the geometric median, not about defining it. So now I'm confused - what is it you really want to know? When you decide, maybe you could edit your question so it accords with what you actually want to ask. – 2012-04-15

0@GerryMyerson: i have calculated it by calculating centroid first. – 2012-04-15
-
0So why do you say in your question that you are unable to calculate it? It seems you don't really have a question. – 2012-04-15
-
0Nope. that is not the case. currently i am first calculating `centroid` of the points, then going to calculate `Geometric median`. I thought that there should be any other way to calculate `Geometric median`. – 2012-04-15

0Sorry, I'm still not with you. If you have a way to calculate the geometric median by first calculating the centroid, then your question shouldn't say "I am still unable to calculate the geometric median." And I still don't know whether, asked Harald asked, you tried out the algorithm in the wikipedia article. – 2012-04-17
-
0Ohhh... Come on man... anyway, do you know about any other way for calculating `Geometric median`? – 2012-04-17
-
0I don't know *any* way to calculate the geometric median. I know Harald has pointed you toward a way, and I infer that you aren't happy with that way, but I don't know what you find unsuitable about the wikipedia way. Also, if you want to be certain I will see your comments, please preface them with @Gerry. – 2012-04-18

0I expand a little on the Wikipedia entry at http://math.stackexchange.com/questions/1401128/how-can-i-find-an-optimal-point-on-a-scatter-graph/1401262#1401262 – 2015-08-19
