Cool function thanks. It'd be great to add an option for controlling the colors when using multiple levels.

Same error as CH for me.

14 Mar 2013 Mann-Whitney-Wilcoxon test Mann-Whitney-Wilcoxon non parametric test for two unpaired groups. Author: Giuseppe Cardillo JR King

Thank you for your quick response.

Your roc function is indeed very good.

For those who would just want a quick measure of effect size, it's easy to perform the empirical AUC from Giuseppe Cardillo's function by adding:
STATS.auc = U / (L(1)*L(2));

Thank you very much for this useful function.

Is it normal that the p-values it makes are different from those obtained with matlab's ranksum function:
[p h stats] = ranksum(1:100,11:110)
p: 0.0203

stats = mwwtest(1:100,11:110)
stats.p: 0.0102

If so, which one shall we report?

As an addup, I think it would be great to add an output of the effect size using the area under the curve, as well as the confidence interval.

Very nice.

Could you add options to include other types of randomness (gaussian etc)?

Thank you!

Best

14 Feb 2013 Conditionally Colored Plot (CCPLOT) Plots conditionally colored (2D line) graphs. Author: Michael Heidingsfeld JR King

Thanks. It would be nice however to allow multiple line plotting such as: ccplot(1:10,rand(200,10),c,map)

Hi,
Is it normal that if I do:
stats = wilcoxon(rand(1,100),rand(1,100))
it return a p-value of 0?
Thanks

22 Oct 2012 colAUC Calculates Area under ROC curve (AUC) for a vector or for each column of a matrix. Author: Jaroslaw Tuszynski JR King

Thanks a lot, very useful.

I would remove the absolute computation: ( auc = 0.5 + abs(0.5-auc);) as it is indicative of the effect direction which is necessary for most statistical analyses.

Impressively efficient.
However, it doesn't export changes of line width for transparent patches, even in png.

Thanks

I encountered the following problem under ubuntu.

Warning: You are using gcc version "4.4.3-4ubuntu5)". The earliest gcc version supported
with mex is "4.1". The latest version tested for use with mex is "4.2".
To download a different version of gcc, visit http://gcc.gnu.org

paretofront.c: In function ‘paretofront’:
paretofront.c:83: error: expected expression before ‘/’ token

mex: compile of ' "paretofront.c"' failed.

The way to solve it is to delete the comment at line 83 in the paretofront.c file.
