[OctDev] Plotting empirical CDFs

[Dr. A. K. <Ale...@ma...>]

Hello,

the other day I had to compare empirical cumulative distribution functions with analytical ones, and I came up with the attached function file to plot the differences, like for example

p=normcdf(randn(1e6,1),0,0.9);
plot_deviation_from_uniform_cdf(p,5)

figure

p=normcdf(randn(1e6,1),0.1,1);
plot_deviation_from_uniform_cdf(p,5)

figure

p=expcdf(exprnd(2,1e6,1),0.5);
plot_deviation_from_uniform_cdf(p,4)

Do you think it could be useful in any package?

If so, I'd document and submit it.

Later,

	Alex
