Dear James,
I'm not sure these are quite what you are after, but I'm suggesting them
anyway. There were several papers from Gordon Barr about non-parametric
methods:
SNAP-1D: a computer program for qualitative and quantitative powder
diffraction pattern analysis using the full pattern profile
Barr, G., Gilmore, C. J., Paisley, J., J. Appl. Cryst. (2004). 37, 665–668
A longer reading list is here:

You can find similar functionality in the panalytical software:
"The HighScore suite" Thomas Degen, Mustapha Sadki, Egbert Bron, Uwe
König and Gwilherm Nénert. Powder Diffraction,
http://dx.doi.org/10.1017/S0885715614000840
A related development would be "XRD-CT". This is computed tomography via
"powder" diffraction by raster scanning a small beam across a large
sample (and rotating).
J. Appl. Cryst. (2014). 47, 1107-1117 [ doi:10.1107/S1600576714008218 ]
XRDUA: crystalline phase distribution maps by two-dimensional scanning
and tomographic (micro) X-ray powder diffraction
W. De Nolf, F. Vanmeert and K. Janssens
It seems that the colours in resulting pictures are "semi-quantitative",
but perhaps not in the sense you had in mind.
All the best,
Jon

Hello All,
I had the following request from a client:
"I am looking for examples of statistics used on semi-quantitative
data, i.e. comparing XRD results of multiple samples. Do you have any
recommendations or know of any papers that clearly explain their
statistical methods? In so many papers, it is glossed over. I have a
pretty good handle on my stats, but would prefer to see what other
have done with XRD datasets."
Can anyone help with this.? I do not know of any of the top of my head.
Thanks in advance,
James Talbot
