# What is quantile normalization?

Is anyone familiar with quantile normalization? As I understand it's a way to "polish" a set of datasets so that they have the same "statistical properties" (according to Wikipedia)? I wonder if anyone knows what are the statistical properties that they refer to when they say

quantile normalization is a technique for making two distributions identical in statistical properties.

Are those statistical properties the mean, median, or standard deviation?

Of possible interest (although it focus on genetics): How does quantile normalization work? –  chl Jan 24 '12 at 20:54
The Wikipedia description sounds an awful lot like a sample-based version of the Probability integral transform between two continuous distributions. –  whuber Jan 24 '12 at 21:31
