Compatibility test

Comparing sample properties:


  p = 1 - \text{erf} \left( \frac{t}{\sqrt{2}} \right)\ \with
  t = \frac{|x\ex - x\ob|}{\sqrt{\sigma\ex^2 + \sigma\ob^2}}
  • x\ex and x\ob are the expected and observed values
  • \sigma\ex and \sigma\ob are their absolute errors

. . .

At 95% confidence level, the values are compatible if:


  p > 0.05
