psStats validation tests

2013-10-16

For these tests, I generated 1e5 sample distributions. The mean of the sample distributions was set to 0.0, and the sigma value randomly drawn from the range [0:100]. For each of these distributions, I drew 1e5 samples, and placed them in a psVector type, and passed this to psVectorStats to calculate the sample mean/stdev, clipped mean/stdev, robust median/stdev, and fitted mean/stdev. In addition, the first row shows the "direct" measurements, the mean and standard deviation values calculated directly from the sample values.
