comment How to keep labels inside the box in BarChart3D
It does! @Kuba, you should post it as answer; happy to accept it. PlotRangePadding -> .35 is just perfect :)

comment How to keep labels inside the box in BarChart3D
@Kuba, thanks for asking. BarChart3D rotate the labels as you change the point of view. The 3D position and overall size seem ok for very short labels as shown in first picture, but for longer labels it seems there is not enough room to display and they overflow the bottom plane. It is a little bit pedantic on my side, I am afraid, but if there is an option to change some position or size I am willing to spend some time perfecting the drawing ;-)

comment Why does Mathematica evaluate Sin[2.0] but not Sin[2]?
Funnily enough, @DonComo, this N[Sin[2], 2]^2 + N[Cos[2], 2]^2 == 1 is True, although you may get a very different result in traditional programming languages. Here is what you get in Ruby (irb): ` Math.sin(2).round(2)**2 + Math.cos(2).round(2)**2 == 1` => false. The reason is that Mathematica keeps track of precision and, at the level of precision requested, the two expressions are the same :)

comment Measuring fractal dimension of natural objects from digital images
@VitaliyKaurov, glad you liked it. Note that Viola & Jones rightly pointed out a link between integral image and Haar wavelet basis in their paper; although this wasn't explored further. It is unclear to me the link between the paper you mentioned and fractal dimension, but certainly worth reading as I am interested in these kind of problems. Cheers.

comment Better way to get Fisher Exact?
Thanks a lot @romke-bontekoe. This is for someone who expects/needs p-values as practiced usually in medicine research, i.e. from a frequentist point of view. Do you know any support of this Bayesian view in medicine/genetics? Interestingly enough, your examples are suitable for Pearson's $\chi^2$, although the test in this context is whether one has an expected matrix having the same row and column sums as the data or not. In a Bayesian view, prior knowledge of both, row and column sums, right? Again, thanks, very interesting!
