Could anyone help me with this?Thanks!! 0 Comments Show all comments Tags histogram;random error; distribution Products No products are associated with this question.

first introduced by Karl Pearson.[1] To construct a histogram, the first step is to "bin" the range of values—that is, divide the entire range of values into a series of https://www.mathworks.com/matlabcentral/answers/166867-histogram-of-error-distribution intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins (intervals) must be adjacent, and are often (but are not required to be) of equal size.[2] If the bins are of equal size, a rectangle is erected over the bin with height proportional to the https://en.wikipedia.org/wiki/Histogram frequency — the number of cases in each bin. However, bins need not be of equal width; in that case, the erected rectangle is defined to have its area proportional to the frequency of cases in the bin[3] The vertical axis is then not the frequency but frequency density — the number of cases per unit of the variable on the horizontal axis. A histogram may also be normalized to display "relative" frequencies. It then shows the proportion of cases that fall into each of several categories, with the sum of the heights equaling 1. Examples of variable bin width are displayed on Census bureau data below. As the adjacent bins leave no gaps, the rectangles of a histogram touch each other to indicate that the original variable is continuous.[4] Histograms give a rough sense of the density of the underlying distribution of the data, and often for density estimation: estimating the probability density function of the underlying variable. The total area of a histogram used for probability density is always normalized to 1.

However, it's worth knowing that histograms aren't typically considered to be a very good way to visualize a univariate distribution. Kernel density plots are generally considered to be better. These are estimated by drawing a very small distribution (typically normal) for each data point. The mean is centered on the datum in question; what's needed then is to determine the SD for the distributions (there are some fairly standard algorithms for this). Once all of the distributions have been drawn, the vertical positions of these drawn distributions are summed at each point on the horizontal axis, and that set of (x,y) pairs forms the final curve that's plotted (there's a very good figure at the linked Wikipedia page). What you could do is use your known variances for each point instead. This will most likely require a little programming on your part, but shouldn't be too hard. share|improve this answer answered Feb 27 '13 at 2:09 gung 73.9k19160309 thank you very much for your answer, summing the kernel densities will do the trick –zamazalotta Feb 27 '13 at 2:43 You're welcome, @zamazalotta.

I tried bincentres = -85:10:85; nelements = [1,4,14,24,46,57,63,63,174,147,69,49,22,9,4,2,1,0]; err = sqrt(nelements); bar(bincentres, nelements); hold on errorbar(bincentres,nelements, err); hold off Previously I was not getting errorbar because I was missing 'bincentres' in 'errorbar' in above code. Thanks to @Shai for pointing out that. But apart from error bar, now I get a line joining middle of each error bar. I want to skip that blue line. matlab plot histogram share|improve this question edited Nov 6 '13 at 11:42 asked Nov 6 '13 at 11:10 user3090650 Use errobar with a linespec that specifies no line. E.g. errorbar(bincenters, nelements, err, '.'). Check doc linespec if you'd like any other marker than the simple dot. –sebastian Nov 6 '13 at 11:48 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted Try errorbar( bincenters, nelements, err ); share|improve this answer answered Nov 6 '13 at 11:12 Shai 46.8k1571150 Thanks for the quick response. It puts the error bar exactly above bar which I want. However, it also joins the middle of each error bar with a line. Is it possible to skip that line. –user3090650 Nov 6 '13 at 11:22 @raj it is very unclear what you want using these descriptions. Can you please post the results you are currently getting, and a more clear description of what you actually want? –Shai Nov 6 '13 at 11:24 thanks for nice comment. I edited my question for clarity. However, I don't know how to include figure here. –user3090650 Nov 6 '13 at 11:45 @raj I believe you need a certain reputation to upload images directly to your question.
