## Samples
## Results compatibility
- Sample $L$: N = 50'000 points following $L_(x)$
- Sample $M$: N = 50'000 points following $M_{\mu \sigma}(x)$
Comparing results:
$$
p = 1 - \text{erf} \left( \frac{t}{\sqrt{2}} \right)\ \with
t = \frac{|x\ex - x\ob|}{\sqrt{\sigma\ex^2 + \sigma\ob^2}}
$$
- $x\ex$ and $x\ob$ are the expected and observed values
- $\sigma_e$ and $\sigma_o$ are their absolute errors
. . .
At 95% confidence level, the values are compatible if:
$$
p > 0.05
